[PATCH v4 3/3] media: nxp: imx8-isi: Add additional 32-bit RGB format support

[Guoniu Zhou]

Add support for additional 32-bit RGB pixel formats (BGRA32, RGBA32,
BGRX32, RGBX32, ARGB2101010).

Formats with alpha channel (BGRA32, RGBA32) only support capture as
ISI ignores alpha bits when reading from memory.

Changes in v3:
- Drop M2M_OUT for ABGR32/BGRA32/RGBA32 as ISI ignores alpha bits (Laurent)
- Remove Android requirements from commit message as alpha formats
  cannot be used as M2M input (Laurent)
- Add Tested-by tag from Laurent Pinchart

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