[PATCH -next v2] usb: Mark sync_all_pins() with static keyword

[Zou Wei]

Fix the following sparse warning:

./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
Mark it static as suggested.

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