[PATCH v3 2/5] media: imx8-isi: Extend output format mask to 7 bits

[Guoniu Zhou]

The ISI output format field width differs across SoC generations:
i.MX8 series (MN/MP/QM/QXP) use a 6-bit field (bits 29:24), while
from i.MX8ULP onwards (including i.MX91/93/95/952) the field is
extended to 7 bits (bits 30:24) to support RAW32 and RAW14 formats.

Extend CHNL_IMG_CTRL_FORMAT_MASK to 7 bits unconditionally since
bit 30 is unused on older platforms.

Changes in v3:
- Use unconditional 7-bit mask instead of per-platform approach (Laurent)
- Drop Reviewed-by from Frank Li due to significant change

Changes in v2:
- Add Reviewed-by tag from Frank Li
