GPIO: Move definition of alternate functions to gpio.inc
This is a straightforward conversion of existing tables
into X-Macro style definitions for the GPIO alternate
functions. This change in itself, is not particularly
powerful, but having all GPIO settings in a single file
makes a board easier to understand.

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