usb: misc: brcmstb-usb-pinmap: Make sync_all_pins static

Fix the following sparse warning:

drivers/usb/misc/brcmstb-usb-pinmap.c:219:6: warning: symbol 'sync_all_pins' was not declared. Should it be static?

The sync_all_pins has only call site within brcmstb-usb-pinmap.c
It should be static

Fixes: 517c4c44b323 ("usb: Add driver to allow any GPIO to be used for 7211 USB signals")
