Subject: [PATCH v6 11/19] acpi/generic_event_device: add logic to detect if HEST addr is available
Create a new property (x-has-hest-addr) and use it to detect if
the GHES table offsets can be calculated from the HEST address
(qemu 10.0 and upper) or via the legacy way via an offset obtained
from the hardware_errors firmware file.
