GPIO: Move STM32 specific gpio_enabled_clocks

Browse Source 
This function should not be part of the public GPIO API.  It is only
available and used in the STM32 implementation.  This moves the
prototype to a chip specific gpio.h that is used within the STM32 chip
directoy.

BRANCH=None
BUG=None
TEST=make buildall -j
     Manually verify GPIO functionality on discovery board
