rambi: Add duplicate GPIO outputs for proto 2.0 board
Proto 2.0 makes these changes:
KBD_IRQ# moves from PM4 to PM3.
EC_PWROK moves from PH2 to PJ1.
Since PM3 and PJ1 are unused on proto 1.5, it's harmless to duplicate
the current functionality on those outputs. We can remove the old
outputs when we deprecate the 1.5 boards.
