[v3,0/3] drm: rockchip: vop2: Add VP clock resets support

Message

The clock reset must be used when the VOP is configured. Skipping it can
put the VOP in an unknown state where the HDMI signal is either lost or
not matching the selected mode.

This adds support for rk3588(s) based SoCs.

Changes since v2:
- Rebase on latest master
- Add details on how to reproduce the issue

Changes since v1:
- Add AXI and AHB clock resets
- Set maxItems for !rk3588 in vop2 bindings

while it isn't that important for this short series, please try to
order things like:
- dt-binding-change
- driver implementing that binding
- dts-file change

because generally, dt-binding + driver changes go through one tree
while the dts-file changes go through another.
