usb: host: cdns3: forward lost power information to xhci

cdns3-plat can know if power was lost across system-wide suspend.
Forward that information:

 - Grab the lost_power bool from cdns_role_driver::resume(). Store it
   into the power_lost field in struct xhci_plat_priv.

 - xhci-plat will call xhci_resume() with that value (ORed to whether we
   are in a hibernation restore).
