usb/xhci: move xhci_gen_setup() away from -pci.
xhci_gen_setup() is generic so it can be used to perform the bare xhci setup even on non-pci based platform. The typedef for the function pointer is moved into the headerfile Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
