I don't think adding new variables here and restricting most of this
logic to xhci-plat.c (in the next patch) is the best way to do it.
There's no conceptual reason why other host controllers (e.g. xhci-pci
or even EHCI) could not have a similar need to tune their PHY after
reset. PHYs are universal to all host controllers.
There is already a 'phy' member in struct usb_hcd which I think is
mostly unused right now. I think it would be much less
confusing/redundant to reuse that member for this purpose (you could
still set it up from xhci_plat_probe(), and then call it from
hcd_bus_resume() or something like that). Since XHCI host controllers
already conveniently have two struct usb_hcd (one for 2.0 and one for
3.0), you can cleanly store references to your two PHYs in there.
