Add support for the QC08C color format in both the encoder and decoder
paths of the iris driver. The changes include:
- Adding QC08C format handling in the driver for both encoding and
decoding.
- Updating format enumeration to properly return supported formats.
- Ensuring the correct HFI format is set for firmware communication.
-Making all related changes required for seamless integration of QC08C
support.
The changes have been validated using v4l2-ctl, compliance, and GStreamer (GST) tests.
Both GST and v4l2-ctl tests were performed using the NV12 format, as
these clients do not support the QCOM-specific QC08C format, and all
tests passed successfully.
During v4l2-ctl testing, a regression was observed when using the NV12
color format after adding QC08C support. A fix for this regression has
also been posted [1].
