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.
BUG=chromium:471331
BRANCH=none
TEST=Flashed ec to samus and samus_pd, verified lightbar tap, lid, power
button, keyboard, charging, all still working.
TEST=Moved a GPIO_INT declaration after a GPIO declaration and watched the build
fail.
TEST=make -j BOARD=peppy tests
TEST=make -j BOARD=auron tests
TEST=make -j BOARD=link tests
