[3.14 FIX][PATCH] bcma: gpio: register all 32 GPIOs

["Rafał Miłecki" <zajec5@gmail.com>]

Broadcom boards have 32 GPIOs (not 16) and these higher ones are
actually used on some devices (for buttons, reset of WiFi devices).

Similar patch may be needed for ssb, however I didn't meet any ssb SoC
with GPIOs 16-31 connected to anything.
This is so trivial I hope it can go as a fix for 3.14. It allows support
for some devices that use these higher GPIOs.
