[PATCH v15 03/10] acpi: add build_append_ghes_generic_data() helper for Generic Error Data Entry

[Dongjiu Geng <gengdongjiu@xxxxxxxxxx>]

It will help to add Generic Error Data Entry to ACPI tables
without using packed C structures and avoid endianness
issues as API doesn't need explicit conversion.
