Add wake signal to PCH
This works similar to SCI/SMI events, but triggers a separate
level-sensitive signal to the PCH instead.
Signed-off-by: Randall Spangler <rspangler@chromium.org>
BUG=chrome-os-partner:8514
TEST=manual
From EC console:
gpioget PCH_WAKEn --> should be 1
hostevent wake 0x1
close lid switch (with magnet)
hostevent -> should show wake mask 0x1, raw events 0x1
gpioget PCH_WAKEn --> should be 0
hostevent clear 0x1
hostevent -> should show raw events 0
gpioget PCH_WAKEn --> should be 1
