usb: pci_quirks: fix sparse 'symbol not declared' warning

This commit fixes the following sparse warning:

drivers/usb/host/pci-quirks.c:
- 252: warning: symbol 'usb_hcd_amd_remote_wakeup_quirk' was not
declared. Should it be static?

This function is exported so the fix was to add it's declaration to the
header file.
