chromeec: Fix logging of EC wake events
The EC behavior for reading events from the ACPI interface was broken
with this commit:
d899fda lpc: ACPI query-next-event drops masked events
https://chromium-review.googlesource.com/194935
This is causing no EC wake events to be logged. To make sure they are
logged once again set the wake mask before querying for events.
Also remove the check for port80 event logging since this is no longer
used as we now store the port80 code in CMOS and this is unnecessary
commands to do for the resume path.
BUG=chrome-os-partner:32462
BRANCH=samus,auron
TEST=build and boot on samus, check for EC wake events for keyboard
and lid in the event log.
