From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

As a GED error device is now defined, add another type
of notification.

Add error notification to GHES v2 using a GED error device GED
triggered via interrupt.

[mchehab: do some cleanups at ACPI_HEST_SRC_ID_* checks and
 rename HEST event to better identify GED interrupt OSPM]
