Subject: [PATCH v5 13/20] dt-bindings: display: rockchip: analogix-dp: Add support for RK3588

Compared with RK3288/RK3399, the HBR2 link rate support is the main
improvement of RK3588 eDP TX controller, and there are also two
independent eDP display interfaces on RK3588 Soc.

The newly added 'apb' reset is to ensure the APB bus of eDP controller
works well on the RK3588 SoC.

Signed-off-by: Damon Ding <damon.ding@...k-chips.com>

- Add the main defferences of the RK3588 eDP and the previous versions
  in commit message

Changes in v3:

Changes in v4:
- Remove 'spdif' clock which added in v3
- Add the comment of newly added 'apb' reset in commit message

Changes in v5:
- Put the differences between RK3288/RK3399 and RK3588 into 'allOf'
