usb: xhci: Mark two functions __maybe_unused
Resolves the following build warnings: drivers/usb/host/xhci.c:332:13: warning: 'xhci_msix_sync_irqs' defined but not used [-Wunused-function] drivers/usb/host/xhci.c:3901:12: warning: 'xhci_change_max_exit_latency' defined but not used [-Wunused-function] These functions are not always used, and since they're marked static they will produce build warnings: - xhci_msix_sync_irqs is only used with CONFIG_PCI. - xhci_change_max_exit_latency is a little more complicated with dependencies on CONFIG_PM and CONFIG_PM_RUNTIME. Instead of building a bigger maze of ifdefs in this code, I've just marked both with __maybe_unused.
