cleanup: Add warning comment to gpio.inc files
With commit e9883124ff16, a GPIO_INT macro was added. That change
also required that all instances of GPIO_INT in a board's
gpio.inc file come before any GPIO macros, or the interrupt
handler wouldn't work properly.
This CL just adds a warning comment about requirement to all
gpio.inc files.
BUG=chromium:471331
BRANCH=none
TEST=make buildall, test image on Cr50
This is a change to comments only. There is no new behavior to
verify, although I did run try out one new image just to be sure
nothing stupid happened.
