Our existing GPIO macros use port# / gpio#, but the concept of different
GPIO ports does not exist on the mec1322. Therefore, add new GPIO macros
for chips which do not have distinct GPIO ports.

In the gpio_info struct, we had a irq_handler pointer defined even
though a majority of the GPIOs did not have irq handlers associated. By
removing the irq_handler pointer out of the struct, we can save some
space with some targets saving more than others. (For example, ~260
bytes for samus_pd).
This change also brings about a new define:
GPIO_INT(name, port, pin, flags, signal)
And the existing GPIO macro has had the signal parameter removed since
they were just NULL.
GPIO(name, port, pin, flags)
In each of the gpio.inc files, all the GPIOs with irq handlers must be
defined at the top of the file. This is because their enum values from
gpio_signal are used as the index to the gpio_irq_handlers table.

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.
