Subject: [PATCH v6 0/9] MediaTek DRM - DSI driver cleanups

Changes in v6:
 - Moved default case from patch [4/9] to patch [3/9]

Changes in v5:
 - Changed patch 1 to not fix the DSI_PS_SEL mask for newer SoCs

Changes in v4:
 - Added a fix for RGB666 formats setting and for wrong register
   definitions for packed vs loosely packed formats
 - Added a commit to make use of mipi_dsi_pixel_format_to_bpp() helper
   instead of open coding the same

Changes in v3:
 - Rebased over next-20240131
 - Added bitfield.h inclusion in patch 3
 - Added three more cleanup commits to the mix to simplify
   the probe function and remove gotos.

Changes in v2:
 - Rebased over next-20231213

This series performs some cleanups for mtk_dsi, enhancing human
readability, using kernel provided macros where possible and
also reducing code size.

Tested on MT8173 and MT8192 Chromebooks (using a DSI<->DP bridge)
and on MT6795 Sony Xperia M5 (DSI video mode panel).
