The struct iris_fmt unites pixfmt with the plane type, however the type
from the struct is not actually used. Drop the struct completely and use
u32 pixfmt in all the callsites.

Changes in v2:
- Made platform_fmts_sm8250_dec const (Dikshita)
- Sorted entries in find_format_by_index (Dikshita)
- Link to v1: https://lore.kernel.org/r/20260311-iris-remote-fmts-v1-1-de0044453b68@oss.qualcomm.com
