mec1322: Allow multiple hibernate wake sources
Allow multiple GPIOs to wake the EC from hibernate by requiring boards
to define hibernate_wake_pins and hibernate_wake_pins_used. In addition,
clean up the GPIO-skipping hibernate code, and skip setting PCH_RTCRST
as an input due to a bug on certain boards.
BUG=chrome-os-partner:42104
TEST=Manual on Glados. Run 'hibernate' from EC console, verify that EC
wakes with power button press or with "dut-control lid_open:no".
BRANCH=None
