The Hantro mainline driver has been used in production
since several years and was only kept as a staging driver
due the stateless CODEC controls.
Now that all the stateless CODEC controls have been moved
out of staging, graduate the driver as well.

Now that the JPEG header length is aligned with bus access boundaries,
the JPEG encoder can output to the capture buffers directly without
going through a bounce buffer.
Do just that, and get rid of all the bounce buffer related code.

Encoders typically operate on macroblocks. Thus their output or coded
resolution is constrained to multiples of macroblocks. For frame sizes
not aligned to macroblocks, cropping is needed to limit the visible
area of the frame.
Add support for cropping on the output (source) side for encoders,
using the selection API.

The Hantro H1 hardware can crop off pixels from the right and bottom of
the source frame. These are controlled with the H1_REG_IN_IMG_CTRL_OVRFLB
and H1_REG_IN_IMG_CTRL_OVRFLR in the H1_REG_IN_IMG_CTRL register.
The ChromeOS kernel driver that this was based on incorrectly added the
_D4 suffix H1_REG_IN_IMG_CTRL_OVRFLB. This field crops the bottom of the
input frame, and the number is _not_ divided by 4. [1]
Correct the name to avoid confusion when crop support with the selection
API is added.

The JPEG encoder found in the Hantro H1 encoder block only produces a
raw entropy-encoded scan. The driver is responsible for building a JPEG
compliant bitstream and placing the entropy-encoded scan in it. Right
now the driver uses a bounce buffer for the hardware to output the raw
scan to.
In commit e765dba11ec2 ("hantro: Move hantro_enc_buf_finish to JPEG
codec_ops.done"), the code that copies the raw scan from the bounce
buffer to the capture buffer was moved, but was only hooked up for the
Hantro H1 (then RK3288) variant. The RK3399 variant was broken,
producing a JPEG bitstream without the scan, and the capture buffer's
.bytesused field unset.
Fix this by duplicating the code that is executed when the JPEG encoder
finishes encoding a frame. As the encoded length is read back from
hardware, and the variants having different register layouts, the
code is duplicated rather than shared.

On a system with multiple encoders present, it's possible for two
encoders to write to the global luma and chroma quantization tables at
the same time if they both submit a JPEG frame to be encoded. Avoid
this race by moving the tables into the `jpeg_ctx` structure which is
stored on the stack.

hantro_enc_buf_finish is used only for JPEG, and so should
be moved to JPEG codec_ops.done.
This cleanup is also taking care of addressing
a subtle issue: checking the non-NULL bounce buffer
using ctx->jpeg_enc, which is a member of a union is
confusing and error-prone.
Note that the issue is currently innocuous because an
encoder context only supports JPEG.
The codec_ops.done has an argument that codec-specific code
shouldn't need, so drop that as well.

Luma and chroma qtables need to be written into two 16-register blocks,
each table consisting of 64 bytes total. The blocks are contiguous and
start at offset 0 for luma and at offset 0x40 for chroma.
The seemingly innocent optimization of writing the two blocks using one
loop causes side effects which result in improper values of quantization
tables being used by the hardware during encoding. Visually this results
in macroblocking artifacts around contrasting edges in encoded images. The
artifacts look like horizontally flipped shadows of the said edges.
Changing the write operations to non-relaxed variant doesn't help.
This patch removes this premature optimization and after this change the
macroblocking artifacts around contrasting edges are gone.

The quantization tables as defined in the file (luma_q_table,
chroma_q_table) are in fact in linear order. The JPEG file header, which is
not generated by the hardware, but must be programatically created with the
CPU, expects the table in zigzag order. On the other hand, the hardware
doesn't expect neither linear, nor zigzag order. Instead it expects the
quantization tables in vertical groups of four quantization parameters,
and the groups are organized in blocks of two vertically adjacent groups.
On top of that the blocks must be provided to the hardware in this order:
leftmost top block, leftmost bottom block, second leftmost top block,
second leftmost bottom block and so on. So, if this is the quantization
table in linear order:
0x10, 0x0b, 0x0a, 0x10, 0x18, 0x28, 0x33, 0x3d,
0x0c, 0x0c, 0x0e, 0x13, 0x1a, 0x3a, 0x3c, 0x37,
0x0e, 0x0d, 0x10, 0x18, 0x28, 0x39, 0x45, 0x38,
0x0e, 0x11, 0x16, 0x1d, 0x33, 0x57, 0x50, 0x3e,
0x12, 0x16, 0x25, 0x38, 0x44, 0x6d, 0x67, 0x4d,
0x18, 0x23, 0x37, 0x40, 0x51, 0x68, 0x71, 0x5c,
0x31, 0x40, 0x4e, 0x57, 0x67, 0x79, 0x78, 0x65,
0x48, 0x5c, 0x5f, 0x62, 0x70, 0x64, 0x67, 0x63
then the hardware expects this in its consecutive registers:
0x100c0e0e,
0x0b0c0d11,
0x12183148,
0x1623405c,
0x0a0e1016,
0x1013181d,
0x25374e5f,
0x38405762,
and so on.
Consequently, the same area of memory cannot be used both for dumping it
into the JPEG file header and writing its contents to the hardware
registers. Instead, a separate pair of arrays is added for properly
reordered quantization tables, to be read with get_unaligned_be32()
and linearly written to the registers.
The "ctx" parameter is not needed any more for hantro_jpeg_get_qtable().

Since (luma/chroma)_qtable is an array of unsigned char, indexing it
returns consecutive byte locations, but we are supposed to read the arrays
in four-byte words. Consequently, we should be pointing
get_unaligned_be32() at consecutive word locations instead.

Rename the driver and all relevant identifiers from Rockchip to Hantro,
as other Hantro IP based VPU implementations can be supported by the
same driver.
The RK3288 decoder is Hantro G1 based, the encoder is Hantro H1.
