xhci:Remove unused marco definitions from the file xhci-hub.c

This removes the unneeded marco definitions for the marcos
of XHCI_PORT_RW1S, XHCI_PORT_RW1C, XHCI_PORT_RW and
XHCI_PORT_RZ due to no uses of these marcos in the file xhci-hub.c or any other related kernel source code file related to supporting xhci host controllers.
