d6dc3cdcc8 drm/mediatek: Add ovl_adaptor get format function 
1. Add ovl_adaptor get_format and get_num_formats component function.
The two functions are needed for getting the supported format in
mtk_plane_init().
2. Get supported format from the ovl_adaptor's rdma engine - mdp_rdma.

453c336463 drm/mediatek: Add ovl_adaptor support for MT8195 
Add ovl_adaptor driver for MT8195.
Ovl_adaptor is an encapsulated module and designed for simplified
DRM control flow. This module is composed of 8 RDMAs, 4 MERGEs and
an ETHDR. Two RDMAs merge into one layer, so this module support 4
layers.

f287c66a60 drm/mediatek: Refactor pixel format logic 
Add an DDP component interface for querying pixel format support
and move list of supported pixel formats into DDP components
instead of mtk_drm_plane.c

ba99d08da6 drm/mediatek: Add lut diff flag for new gamma hardware support 
mt8183 gamma module usage is different with before soc,
gamma odd(index start from 0) lut value set to hardware
register should be
the difference of current lut value with last lut value.

for example, chrome os user space set lut
like this(only r chanel for example):
2 4 6 8 10 12.
1) mt8183 gamma driver should set the gamma lut to hardware
register like this:
2 [2] 6 [2] 10 [2]
the value with [] is the difference value
2)gamma hardware process display data with original lut

b74d921b90 drm/mediatek: Add vblank register/unregister callback functions 
We encountered a kernel panic issue that callback data will be NULL when
it's using in ovl irq handler. There is a timing issue between
mtk_disp_ovl_irq_handler() and mtk_ovl_disable_vblank().

To resolve this issue, we use the flow to register/unregister vblank cb:
- Register callback function and callback data when crtc creates.
- Unregister callback function and callback data when crtc destroies.

With this solution, we can assure callback data will not be NULL when
vblank is disable.
