Subject: [PATCH v3 12/26] media: iris: Fix format check for CAPTURE plane
 in try_fmt

Previously, the format validation relied on an array of supported
formats, which only listed formats for the OUTPUT plane. This caused
failures when validating formats for the CAPTURE plane.
Update the check to validate against the only supported format on the
CAPTURE plane, which is NV12.

Fixes: fde6161d91bb ("media: iris: Add HEVC and VP9 formats for decoder")
