From: Jason-jh Lin <jason-jh.lin at mediatek.corp-partner.google.com>

Some SoCs not support pre-multiplied pixel formats and extending
configuration of OVL pre-multiplied color formats, such as MT8173.

Fix the SoC degradation problem by this sreies.

Change in v5:
Add fix patch for mtk_plane

Change in v4:
Add lost cases of mtk_ovl_fmt_convert_with_blend

Change in v3:
Change MACRO approach to function pointer in driver data

Change in v2:
Fix build error and typo

Change in v1:
Add fix patch for OVL unsupport color format settings by driver data

Jason-JH.Lin (2):
  drm/mediatek: ovl: Add fmt_convert function pointer to driver data
  drm/mediatek: Add blend_modes to mtk_plane_init() for different SoCs
