gpio: Replace duplication in gpio declarations with X-macro file

Previously each board.h and board.c contained an enum and an array
for gpio definitons that had to be manually kept in sync, with no
compiler assistance other than that their lengths matched.

This change adds a single gpio.inc file that declares all gpio's
that a board uses and is used as an X-macro include file to
generate both the gpio_signal enum and the gpio_list array.
