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.

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.
