A recent patch caused an unused-function warning in builds with
CONFIG_PM disabled, after the function became marked 'static':
drivers/usb/host/xhci-pci.c:91:13: error: 'xhci_msix_sync_irqs' defined but not used [-Werror=unused-function]
91 | static void xhci_msix_sync_irqs(struct xhci_hcd *xhci)
| ^~~~~~~~~~~~~~~~~~~
This could be solved by adding another #ifdef, but as there is
a trend towards removing CONFIG_PM checks in favor of helper
macros, do the same conversion here and use pm_ptr() to get
either a function pointer or NULL but avoid the warning.
As the hidden functions reference some other symbols, make
sure those are visible at compile time, at the minimal cost of
a few extra bytes for 'struct usb_device'.
