This reverts commit b6c61a6c37317efd7327199bfe24770af3d7e799.
The requested pixelformat is being propagated from the capture to the
tpg in the sensor.
This was a bad design choice, as we start having the following issues:
* We set a pixelformat in the capture;
* We set matching media bus formats in the subdevices pads;
* Link validate looks fine (sizes matches, media bus formats matches);
* Issue: if some of the subdevice doesn't know how to generate the
requested pixelformat in the capture, then stream_on fails. This is bad
because capture says it supports that pixelformat, everything looks
fine, but it is not, and there is no way to find it out through the
links.
This patch was implemented so we could request any pixelformat from the
pipeline regardeless of the media bus format configured between pads.
Not all pixelformat can be mapped into a media bus code (e.g.
multiplanar formats), so with this patch we could request those
pixelformats from the tpg.
Solution: map pixelformats to media bus codes as before, and implement
conversions to other pixelformats in the capture to support multiplanar.
So first step to this solution is to revert this patch.

Change the way subdevices check if the stream is running. Verify the stream
pointer instead of src_frame. This makes easier to get rid of the void* and
u8* that points to frames in the subdevices structs.
Remove checks that s_stream does on subdevices. They are redundant since
the Media Controller Framework doesn't allow two streaming on the same
media pipeline at the same time.

Media bus codes were being mapped to pixelformats, which causes a
limitation on vimc because not all pixelformats can be mapped to media
bus codes.
Also, media bus codes are an internal configuration from the device.
Userspace only assures media bus codes matches between pads and expects
the image in a given pixelformat. So we can allow almost any media bus
format to be configured between pads, except for debayer that expects a
media bus code of type bayer in the sink pad.

Use the new v4l2_subdev_internal_ops release op to free the
subdev memory only when the last user closed the file handle.
Move v4l2_device_unregister_subdev() to the end of the
vimc_ent_sd_unregister() function since now the unregister_subdev()
call may free the vimc_ent_device struct which is used after the
unregister_subdev() call. So this now has to be done last.

Add a linear pipeline logic for the stream control. It's created by
walking backwards on the entity graph. When the stream starts it will
simply loop through the pipeline calling the respective process_frame
function of each entity.

At over 4000 #includes, <linux/platform_device.h> is the 9th most

The vimc platform drivers define a platform device ID table but these
are not set to the .id_table field in the platform driver structure.
So the platform device ID table is only used to fill the aliases in
the module but are not used for matching (works because the platform
subsystem fallbacks to the driver's name if no .id_table is set).
But this also means that the platform device ID table isn't used if
the driver is built-in, which leads to the following build warning:
This causes the following build warnings when the driver is built-in:
