ec/google/chromeec/acpi: Add support for DPTF oem variable event notify

The agah EC code will monitor adapter current to choose corresponding
DPTF oem variable table. When it changes, this event will send to the
ACPI FW through host event and then pass onto the DPTF kernel driver.
This patch adds support for that feature.

BUG=b:238921409
TEST=add Printf() calls to the ACPI,
     and check these Printf() will show up in the kernel log
     when EC send oem variable table change notify.
