usb: xhci: fix USB_XHCI_PCI depends

Browse Source 
The xhci-pci-renesas module exports symbols for xhci-pci to load the
RAM/ROM on renesas xhci controllers. We had dependency which works
when both the modules are builtin or modules.

But if xhci-pci is inbuilt and xhci-pci-renesas in module, we get below
linker error:
drivers/usb/host/xhci-pci.o: In function `xhci_pci_remove':
drivers/usb/host/xhci-pci.c:411: undefined reference to `renesas_xhci_pci_exit'
drivers/usb/host/xhci-pci.o: In function `xhci_pci_probe':
drivers/usb/host/xhci-pci.c:345: undefined reference to `renesas_xhci_check_request_fw'

Fix this by adding USB_XHCI_PCI having depends on USB_XHCI_PCI_RENESAS
|| !USB_XHCI_PCI_RENESAS so that both can be either inbuilt or modules.
