platform/chrome: cros_ec: Poll EC log on EC panic

Browse source

Add handler for CrOS EC panic events. When a panic is reported,
immediately poll for EC log.

This should result in the log leading to the EC panic being
preserved.

ACPI_NOTIFY_CROS_EC_PANIC is defined in coreboot at
https://review.coreboot.org/plugins/gitiles/coreboot/+/refs/heads/master/src/ec/google/chromeec/acpi/ec.asl
