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.
