When adding runtime PM support to the Tegra XHCI driver, it is desirable
to move the function calls to enable the clocks, regulators and PHY from
the tegra_xusb_probe into the runtime PM handlers. Currently, the
clocks, regulators and PHY are all enabled before we call
usb_create_hcd() in tegra_xusb_probe(), however, we cannot call
pm_runtime_get_sync() at this point because the platform device data is
not yet initialised. Fortunately, the function usb_create_hcd() can be
called before we enable the clocks, regulators and PHY and so prepare
for adding runtime PM support, by moving the call to usb_create_hcd()
before we enable the hardware.
