1. Always use wake-up control interrupt for keyboard KSI. This can also wake-up EC from deep doze / sleep mode. 2. In keyboard ISR, we just clear interrupt status to prevent keyboard interrupt can't be re-enabled. (for example, a KSI interrupt wakes up keyboard scan task, but keyboard_raw_read_rows() got 0.)
