The hardware path of vdosys1 with DPTx output need to go through by several modules, such as, OVL_ADAPTOR and MERGE.

Add DRM and these modules support by the patches below:

Changes in v4:
- use merge common driver for merge1~4.
- refine ovl_adaptor rdma driver.
- use ovl_adaptor ddp_comp function instead of ethdr.
- modify for reviewer's comment in v3.

Changes in v3:
- modify for reviewer's comment in v2.
- add vdosys1 2 pixels align limit.
- add mixer odd offset support.

Changes in v2:
- Merge PSEUDO_OVL and ETHDR into one DRM component.
- Add mmsys config API for vdosys1 hardware setting.
- Add mmsys reset control using linux reset framework.

Add mmsys config API. The config API is used for config mmsys reg.
Some mmsys regs need to be setting according to the HW engine binding
to the mmsys simultaneously.

Add cmdq support for mtk-mmsys config API.
The mmsys config register settings need to take effect with the other
HW settings(like OVL_ADAPTOR...) at the same vblanking time.

If we use CPU to write the mmsys reg, we can't guarantee all the
settings can be written in the same vblanking time.
Cmdq is used for this purpose. We prepare all the related HW settings
in one cmdq packet. The first command in the packet is "wait stream done",
and then following with all the HW settings. After the cmdq packet is
flush to GCE HW. The GCE waits for the "stream done event" to coming
and then starts flushing all the HW settings. This can guarantee all
the settings flush in the same vblanking.

Among other features the mmsys driver should implement a reset
controller to be able to reset different bits from their space.

For MT8195 vdosys1, many async modules need to reset after
the display pipe stops and restart.

Add mtk-mutex support for mt8195 vdosys1.
The vdosys1 path component contains ovl_adaptor, merge5,
and dp_intf1. Ovl_adaptor is composed of several sub-elements,
so change it to support multi-bit control.

Add merge new API.
1. Vdosys1 merge1~merge4 support HW mute function, so add unmute API.
2. Add merge new advance config API. The original merge API is
   mtk_ddp_comp_funcs function prototype. The API interface parameters
   cannot be modified, so add a new config API for extension.
3. Add merge enable/disable API for cmdq support. The ovl_adaptor merges
   are configured with each drm plane update. Need to enable/disable
   merge with cmdq making sure all the settings taken effect in the
   same vblank.

ETHDR is a part of ovl_adaptor.
ETHDR is designed for HDR video and graphics conversion in the external
display path. It handles multiple HDR input types and performs tone
mapping, color space/color format conversion, and then combine
different layers, output the required HDR or SDR signal to the
subsequent display path.

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.

MT8195 have two mmsys. Modify drm for MT8195 multi-mmsys support.
The two mmsys (vdosys0 and vdosys1) will bring up two drm drivers,
only one drm driver register as the drm device.
Each drm driver binds its own component. The first bind drm driver
will allocate the drm device, and the last bind drm driver registers
the drm device to drm core. Each crtc path is created with the
corresponding drm driver data.
