Support for multiplanar and singleplanar formats is mutually exclusive,
at least in practice. In our attempt to unify support for support for
mplane and !mplane in v4l, let's get rid of the
->vidioc_enum_fmt_{vid,out}_cap_mplane() hooks and call
->vidioc_enum_fmt_{vid,out}_cap() instead.

The last buffer is often signaled by an empty buffer with the
V4L2_BUF_FLAG_LAST flag set. Such buffers were returned with the
bytesused field set to the full size of the OPB, which leads
user-space to believe that the buffer actually contains useful data. Fix
this by passing the number of bytes reported used by the firmware.

Existing code returns the max of the decoded size and buffer size.
It turns out that buffer size is always greater due to hardware
alignment requirement. As a result, payload size given to client
is incorrect. This change ensures that the bytesused is assigned
to actual payload size, when available.

A couple of drivers produced build errors after the mod_devicetable.h
header was split out from the platform_device one, e.g.
drivers/media/platform/davinci/vpbe_osd.c:42:40: error: array type has incomplete element type 'struct platform_device_id'
drivers/media/platform/davinci/vpbe_venc.c:42:40: error: array type has incomplete element type 'struct platform_device_id'
This adds the inclusion where needed.

This is implementing multi-stream decoder support. The multi-stream
will be used to enable/disable the primary/secondary decoder
outputs. Depending on formats on both decoder outputs we could
implement downscale, dithering and supporting UBWC (universal
bandwidth compression) formats. The UBWC compressed raw format is
used to optimize interconnect bandwidth for bigger resolutions
like 4K and hence we will get some power-saving benefits as well.
Both decoder outputs are distinguished by buffer_type field in
the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type
for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary
decoder output.
Starting from Venus 4xx the DPB buffers format must be UBWC, so
the multi-stream becomes mandatory for this Venus version. That
means that we need to allocate internally in the driver a set of
DPB buffers (with UBWC NV12 format) and give them to the firmware.
The other decoder output (we called it OPB) format will be NV12
linear format and with the same resolution (or smaller in case
the user wants to downscale).
The DPB buffers are used for decoder reference frames and those
have to be in a specific format (UBWC). So one decoder output is
used to fill those reference buffers while the other output is
used to fill the userspace buffers with the user requested format.

HFI interface related to the output configuration, and
keep vdec_set_properties() which will set properties

When checking a format for validity, the resolution is reset to 1280x720
whenever the pixel format is not supported. This behavior can mislead
user-space into believing that this is the only resolution supported,
and looks strange considering that if we try/set the same format with
just the pixel format changed to a valid one, the call will this time
succeed without altering the resolution.
Resolution is managed independently of the pixel format, so remove this
reset.

find_format_by_index() stops enumerating formats as soon as the index
matches, and returns NULL if venus_helper_check_codec() finds out that
the format is not supported. This prevents formats to be properly
enumerated if a non-supported format is present, as the enumeration will
end with it.
Fix this by moving the call to venus_helper_check_codec() into the loop,
and keep enumerating when it fails.

This addresses the wrong behavior of decoder stop command by
rewriting it. These new implementation enqueue an empty buffer
on the decoder input buffer queue to signal end-of-stream. The
client should stop queuing buffers on the V4L2 Output queue
and continue queuing/dequeuing buffers on Capture queue. This
process will continue until the client receives a buffer with
V4L2_BUF_FLAG_LAST flag raised, which means that this is last
decoded buffer with data.
