From: Surong Pang <surong.pang@unisoc.com>

Let usb phy shutdown later in xhci_plat_remove function.
Some phy driver doesn't divide 3.0/2.0 very clear.
If calls usb_phy_shutdown earlier than usb_remove_hcd(hcd),
It will case 10s cmd timeout issue.

Call usb phy shutdown later has better compatibility.
