arm64: dts: rockchip: complete USB nodes on ROCK 4D

Browse Source 
The ROCK 4D uses both USB controllers, and both of which in host mode.
However, it still names one of the supplies for them "OTG" in the
schematic.

Fix the "host" supply's input, and add the "otg" supply. Enable the
remaining USB PHY nodes, and the first controller node as well.
