ACPI / APEI / ARM64: APEI initial support for ARM64

Browse source 
This patch provides APEI arch-specific bits for ARM64

Meanwhile,
 (1) Move HEST type (ACPI_HEST_TYPE_IA32_CORRECTED_CHECK) checking to
     a generic place.
 (2) Select HAVE_ACPI_APEI when EFI and ACPI is set on ARM64, because
     arch_apei_get_mem_attribute is using efi_mem_attributes() on
     ARM64.
