[Qemu-devel] [PATCH RESEND v15 01/10] ACPI: add some GHES structures and macros definition

[Dongjiu Geng <gengdongjiu@huawei.com>]

Add Generic Error Status Block structures and some macros
definitions, which is referred to the ACPI 4.0 or ACPI 6.2. The
HEST table generation and CPER record will use them.

Signed-off-by: Dongjiu Geng <gengdongjiu@huawei.com>

Change since v14:
Thanks Igor's review and comments
1. Update spec comment for AcpiHestNotifyType
2. drop () for the macro definition

Change since v13:
1. Clean the new added structures and macros definition

Change since v12:
1. Address Igor's comments to to get rid of most structures and use
build_append_int_noprefix() API to compose whole error status block
and APEI table in [1]
