ec/google/chromeec/acpi: Add MKBP support
Allow EC to send an interrupt using ACPI SMI when a MKBP event
is available. This will be used by the sensor stack.
Update all ACPI branch except those without sensors with:
for i in $(find . -name ec.h -exec grep -l MAINBOARD_EC_SCI_EVENTS {} \+
| cut -d '/' -f 2 | grep -v -e cyan -e lars); do
echo $i
cd $i
git diff ../lars/ec.h | patch -p 5
cd -
done
BUG=b:27849483
BRANCH=none
TEST=Compile on Samus. Tested in Cyan branch.
