[Qemu-arm] [PATCH v12 01/12] ACPI: add related GHES structures and macros definition

[Dongjiu Geng]

Add Generic Error Status Block structures and some macros
definition, which refer to the ACPI 4.0 and ACPI 6.1. The
HEST table generation and CPER record will use them.

Signed-off-by: Dongjiu Geng <address@hidden>

It has been suggested to get rid of most structures that introduced in patch, 
the
second patch mainly use build_append_int_noprefix() API to compose whole error 
status
block and APEI table
