Support multi-bit mask in STM32L's GPIO functions
The definition of GPIO interface allows passing in multi-bit mask, and
this is what's done by gpio_config_module(). Fix STM32L's function so
that it doesn't accidentally set incorrect GPIO register values.
BUG=chrome-os-partner:22605
TEST=On Kirby, do 'led r 0' and check the value of 0x40020800 is
0x01540000.
BRANCH=None
