chromeec: allow override of i8042 interrupt
Some boards need to override which IRQ the i8042 keyboard
controller has its interrupt on instead of the default
IRQ#1. The SIO_EC_PS2K_IRQ macro provides the mainboard
an ability to override the interrupt location.
BUG=chrome-os-partner:23965
BRANCH=None
TEST=Built and booted rambi using this option. New IRQ is correctly
picked up by kernel allowing keyboard support.
