[PATCH v5 3/3] arm64: dts: rockchip: rk356x: Add eDP controller and phy nodes

[Damon Ding <damon.ding@rock-chips.com>]

Add the eDP PHY GRF (with the eDP PHY child node mapped by its own
register window) and the eDP controller nodes for the RK3568/RK3566
SoCs.

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

Changes in v4:
- Model the PHY node with a reg property under the parent syscon.

Changes in v5:
- Move the APB clock (PCLK_EDPPHY_GRF) from the parent syscon node to
  the PHY node, matching the updated binding and driver. (Sashiko)
- Rename the PHY reference clock to "ref", matching the binding.
