Each video device descriptor determines the name, callback ops, and input and
output formats on the corresponding video device. This simplifies coda_enum_fmt
and coda_try_fmt a bit and will simplify adding separate video devices for JPEG
codecs due to the slightly different behavior in the CodaDx6/CODA7542 case and
a separate hardware unit on CODA960.

Since the firmware newer writes to FRAME_MEM_CTRL, we can initialize it once
per context (incidentally, we already do write it in coda_hw_init) and never
have to read it back.

Clearing the aborting flag in stop_streaming is necessary if we want to start
streaming again without having to closing and reopening the device. Also,
do not explicitly set it in default_params; the context is zeroed by
kzalloc anyway.

For several reasons it's good practice to leave devices in runtime PM
active state while those have been probed.
In this cases we also want to prevent the device from going inactive,
until the firmware has been completely installed, especially when using
a PM domain.

Since we neither support composing on the OUTPUT side, nor cropping
on the CAPTURE side, disable VIDIOC_CROPCAP and VIDIOC_G/S_CROP
altogether. This silences a GStreamer warning when GStreamer tries
to obtain the pixel aspect ratio using VIDIOC_CROPCAP.

This patch makes coda_s_fmt_vid_out propagate the output frame size
to the capture side.
The GStreamer v4l2videodec only ever calls S_FMT on the output side
and then expects G_FMT on the capture side to return a valid format.

This patch increases the maximum vertical frame size reported
by enum_fmt and accepted by try_fmt/s_fmt from 1080 to 1088.
Since for 16x16-pixel macroblocks 1080p will be rounded up to
this anyway, we may as well admit that we support it.
