[PATCH 21/22] usb: xhci: move struct 'xhci_port' specific macro

[Niklas Neronin <niklas.neronin@linux.intel.com>]

This macro is not for a USB Port Register, rather specific macro for
struct 'xhci_port'. Because xhci-port.h contains only xHCI specification
macros, move 'DUPLICATE_ENTRY' macro out of xhci-port.h.
