[PATCH 3/7] usb: xhci: plat: Fix suspend/resume when the optional usb_phy exists

Commit 7b8ef22ea547 ("usb: xhci: plat: Add USB phy support") adds the
usb_phy for usb3, but it forgets to shutdown/init the usb_phy in the
suspend/resume path. This patch fixes this issue by adding missing
usb_phy related calls.
