Support MT8188 VDOSYS1 in display driver.

Changes in v5:
- Reuse .clk_enable/.clk_disable in struct mtk_ddp_comp_funcs
  in mtk_disp_ovl_adaptor.c
- Adjust commits order

Changes in v4:
- Add new functions in mtk_disp_ovl_adaptor.c to enable/disable
  components and reuse them when clock enable/disable
- Rename components in mtk_disp_ovl_adaptor.c and sort them in
  alphabetical order

Changes in v3:
- Define macro MMSYS_RST_NR in mtk-mmsys.h and update reset table
- Fix typos (ETDHR -> ETHDR, VSNYC -> VSYNC)
- Rebase dt-bindings on linux-next
- Refine description of Padding
- Squash reset bit map commits for VDO0 and VDO1 into one

Changes in v2:
- Remove redundant compatibles of MT8188 because it shares the same
  configuration with MT8195
- Separate dt-bindings by modules
- Support reset bit mapping in mmsys driver

I'm testing this series with my local MT8188 setup + an external 4K
display, and I feel there is something missing in it.
With these patches the external display can be lit up on my end, but I
only see glitches and no meaningful content is rendered.
Could you check again and send the updated series with the fix?

Thanks,
Fei

Yes, there is a patch for fixing DPI misconfiguration (.input_2pixel =
true), but since I'm not DPI owner, didn't include that in this patch.

Will discuss with DPI owner and merge that fix into this series and re-
send it again if you would like to.
