As per spec, the CAPTURE resolution should be automatically set based on
the OTUPUT resolution. This patch properly propagate width/height to the
capture when the OUTPUT format is set and override the user provided
width/height with configured OUTPUT resolution when the CAPTURE fmt is
updated.
This also prevents userspace from selecting a CAPTURE resolution that is
too small, avoiding unwanted page faults.

Side note, this patch is based on top of "Samuel Holland <samuel@sholland.org>"
patches:
[PATCH v3 1/2] media: cedrus: Program output format during each run
[PATCH v3 2/2] media: cedrus: Implement runtime PM
As the patchset also fixes concurrent decoding issues. This was tested using
GStreamer implementation, which strictly follow the Stateless CODEC spec and
expect OUTPUT to CAPTURE width/height propagation.

It seems this one felt thru the cracks. Sorry for the delay.

Looks like there's no issue with alignment (that will get applied as well),
which was a possible concern.

You can only do this if the capture queue isn't busy.
See also hantro_reset_raw_fmt() where it does that check.
So this needs a v2.

I missed this reply, wasn't expecting a negative third review. I'll
copy and paste from there. So basically:
- EBUSY if peer vq is busy
- EBUSY if pixel format is changed while vq is busy
- EBUSY if streaming
Obviously, I don't have userspace to exercise any of these cases, but
it seems to make sense. I remembered about this patch today as someone
reported the kernel crash we get without this patch:
---
