media: qcom: camss: Add debug message to camss-video format check

Browse Source 
Add a debug trace to video_check_format() to log both the subdev-reported
format and the format requested by the video node. This makes it easier
to diagnose mismatches between subdev output and the negotiated V4L2
pixel format, as well as issues related to plane count, resolution, or
field settings.
