GPIO: Reduce code duplication in STM32 gpio driver
Previously the F0 and L variants had almost identical driver files
and the F variant shared about half of its driver. This refactor
moves the shared code into gpio.c and gpio-f0-l.c, the latter
is for code shared between the F0 and L variants.

BRANCH=none
TEST=make buildall -j
Followed by manual testing of interrupt on change and UART
functionality on STM32F0 based discovery board.
