Enable the USB3-A port by configuring the USB HSPHY with required
regulator supplies and the QMP combo PHY with correct lane assignments
for this fixed USB-A connector.
The QMP combo PHY shares lanes between DisplayPort and USB3 SuperSpeed.
Configure port@0 with two endpoints: endpoint@0 for DP output (lanes
0-1) connected to the HDMI bridge, and endpoint@1 for USB3 SS output
(lanes 2-3). Remove the orientation-switch property as this is a fixed
USB-A connector with no orientation switching.
Add a usb-a-connector node wiring the HS and SS paths to the DWC3
controller and QMP PHY respectively. Set dr_mode to host as this is
a fixed host-only USB-A port.
Tested on Radxa Dragon Q6A (QCS6490) with USB3 SuperSpeed confirmed
via lsusb showing 5000M link speed.

Previous patch needs this change to work, please squash.
