What are these used for? I guess I'll see when I get to the driver
patch.

I think the name for this in the documentation is HVDD_PEX_PLL_E, which
would translate to hvdd-pex-pll-e. At least that's how we named this
supply for PCIe.
Alternatively it seems like there are aliases for the USB 3.0 related
supplies:
avdd-pex-pll -> avdd-usb-ss-pll
hvdd-pex -> hvdd-usb-ss
hvdd-pex-pll-e -> hvdd-usb-ss-pll-e
So perhaps these could be used for the XHCI driver instead? Also, should
these supplies not be mandatory?
