to look at the new patch set (#3).

Change subject: google/chromeec: Add ACPI method for EC Panic

google/chromeec: Add ACPI method for EC Panic

Add an ACPI method to handle EC_HOST_EVENT_PANIC (bit 24) events.

EC panic is not covered by the standard (0-F) ACPI notify values.
Arbitrarily choosing B0 notify, which is in the 84-BF device specific
ACPI notify range.

This will be a no-op until the kernel driver is also updated to handle
this event.

BUG=b:258195448
BRANCH=None
TEST=Observe event with modified cros_ec_lpc driver
