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.
