Thinh Nguyen 2d8466c9a8 usb: xhci-plat: Don't include xhci.h
commit 4a237d5544 upstream.

The xhci_plat.h should not need to include the entire xhci.h header.
This can cause redefinition in dwc3 if it selectively includes some xHCI
definitions. This is a prerequisite change for a fix to disable suspend
during initialization for dwc3.
