Subject: [PATCH v2 0/5] Add components to support PQ in display path for MT8196

Due to the path mux design of the MT8196, the following components need to be configured to support Picture Quality (PQ) in the display path:CCORR0, CCORR1, DITHER0, GAMMA0, MDP_RSZ0, POSTMASK0, TDSHP0.

Change in v2:
- Update compatible name of mt8196-mdp-rsz.
- Update clocks and examples in mdp-rsz dt-bindings.
- Update subject of postmask dt-bindings.
- Remove DISP_REG_MDP_RSZ_EN.
- Add comment for MDP_RSZ size settings.
