Subject: [PATCH v3 0/8] drm/vkms: Add support for multiple plane formats

This series introduce a macro to generate a function to read simple
formats. It avoid duplication of the same logic for similar formats.

PATCH 1 is the introduction of the macro and adaptation of the existing
code to avoid duplication
PATCH 2-6 introduce new formats with the help of this macro.

This series must be applied on top of [1].

Changes in v3:
- Rebased on new YUV iterations
- Link to v2: https://lore.kernel.org/r/20241007-b4-new-color-formats-v2-0-d47da50d4674@bootlin.com

Changes in v2:
- Add proper casting/type to __le16 when needed to avoid warnings with 
  sparse
