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
