When CONFIG_PCI and CONFIG_PM are not selected, xhci.c gets this
warning:
drivers/usb/host/xhci.c:409:13: warning: ‘xhci_msix_sync_irqs’ defined
but not used [-Wunused-function]
It happens due to lack of __maybe_unused flag on xhci_msix_sync_irqs()
function in case of !CONFIG_PCI.

Change v1 -> v2:
- xhci_msix_sync_irqs() already uses __maybe_unused flag when CONFIG_PCI is
set. Proper solution is to add same flag when !CONFIG_PCI instead of define
function as inline.
