Fix a bug that GPIO cannot be set as input on stm32l
GPIO_INPUT is defined as 0, and any GPIO flag cannot be examined against
GPIO_INPUT. Change GPIO_INPUT to non-zero value to avoid this.
BUG=chrome-os-partner:22275
TEST=On Kirby, set a GPIO to output and pull it low, and then set it back to
input. Check it can be pull high externally.
TEST=Build all boards.
TEST=Boot link and spring.
BRANCH=None (unless this bug hits some other boards.)
