In order to reduce flash size on some constrained boards this CL
modifies the GPIO macro in gpio_list.h to change the name field from
that listed 'name' to the concat of 'port' and 'pin'.

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.

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.
