Subject: [PATCH v3 13/13] media: verisilicon: Conditionnaly ignore native formats
AV1 film grain feature requires to use the postprocessor to produce
valid frames. In such case the driver shouldn't propose native pixels
format but only post-processed pixels format.
Additionally if when setting a control a value could change capture
queue pixels formats it is needed to call hantro_reset_raw_fmt().
Signed-off-by: Benjamin Gaignard <benjamin.gaignard@...labora.com>

v3:
- Reset raw pixel formats list when bit depth or film grain feature
values change.
