From: Joseph Chen <chenjh at rock-chips.com>

Add support for the USB 3.0 devices in rk3588:
- USB DRD(dual role device) 3.0 #0 as usbdrd3_0 which is available in
rk3588s
- USB DRD(dual role device) 3.0 #1 as usbdrd3_1 which is available in
rk3588 only
- USB DP PHY (combo USB3.0 and DisplayPort Alt Mode ) #0 phy interface
as usbdp_phy0
- USB DP PHY (combo USB3.0 and DisplayPort Alt Mode ) #1 phy interface
as usbdp_phy1
- USB 2.0 phy #2 , the USB 3.0 device can work with this phy in USB 2.0
mode
- associated GRFs (general register files) for the devices.
