qusb2: Add missing phy regulator calls in shutdown callback



dwc3 implementation sets up the phy using phy init before
adding xhci platform device. xhci platform driver also sets
up phy using init api. This causes phy ldos to be enabled
twice as phy driver does not turn off regulators in shutdown
callback. While at it, remove legacy code which disables the
phy as phy will be disabled in set_suspend callback.
