[PATCH 2/7] usb: xhci: plat: attach the usb_phy to the correct hcd

[Jisheng Zhang <jszhang@marvell.com>]

Commit 7b8ef22ea547 ("usb: xhci: plat: Add USB phy support") adds the
usb_phy for usb3, but it attached the usb_phy to incorrect hcd. The
xhci->shared_hcd is the hcd for usb3, this patch fixes this issue
by attach the usb_phy to the xhci->shared_hcd.
