The variable np in function meson_gx_socinfo_init takes the return value
of of_find_compatible_node, which gets a node but does not put it. If
this node is not put it may cause a memory leak. Hence put np after its
usefulness has been exhausted.
Issue found with Coccinelle.

Add an of_node_put when a tested device node is not available.
The semantic patch that fixes this problem is as follows
(http://coccinelle.lip6.fr):
// <smpl>
@@
identifier f;
local idexpression e;
expression x;
@@
e = f(...);
... when != of_node_put(e)
when != x = e
when != e = x
when any
if (<+...of_device_is_available(e)...+>) {
... when != of_node_put(e)
(
return e;

+ of_node_put(e);
return ...;
)
}
// </smpl>

This adds the:
- G12A SoC ID and S905X2, S905D2 package IDs, found booting the
X96 Max and U200 Reference Board
- G12B SoC ID and S922X package ID, found booting the Odroid-N2
- S805X, S805Y package IDs found in the vendor U-Boot source

When updated IDs on f842c41adc04 ("amlogic: meson-gx-socinfo: Update soc ids")
we introduced packages ids using the full 8bit value, but in the function
socinfo_to_package_id() the id was filtered with the 0xf0 mask.
While the 0xf0 mask is valid for most board, it filters out the lower
4 bits which encodes some characteristics of the chip.
This patch moves the mask into the meson_gx_package_id table to be applied
on each package name independently and add the correct mask for some
specific entries.
An example is the S905, in the vendor code the S905 is package_id
different from 0x20, and S905M is exactly 0x20.
Another example are the The Wetek Hub & Play2 boards using a S905-H
variant, which is the S905 SoC with some licence bits enabled.
These licence bits are encoded in the lower 4bits, so to detect
the -H variant, we must detect the id == 0x3 with the 0xf mask.

I've noticed the following message while booting a S905X based board:
soc soc0: Amlogic Meson GXL (S905D) Revision 21:82 (b:2) Detected
The S905D string is obviously wrong. The vendor code does:
...
ver = (readl(assist_hw_rev) >> 8) & 0xff;
meson_cpu_version[MESON_CPU_VERSION_LVL_MINOR] = ver;
ver = (readl(assist_hw_rev) >> 16) & 0xff;
meson_cpu_version[MESON_CPU_VERSION_LVL_PACK] = ver;
...
while the current code does:
...
...
This means that the current mainline code has package id and minor
version reversed.

Amlogic SoCs have a SoC information register for SoC type, package type and
revision information.
This patchs adds support for this register decoding and exposing with the
SoC bus infrastructure.
