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.

GHES currently maps two pages with atomic_ioremap. From now
on, NMI is architectural depended so there is no need to allocate
an NMI page for platforms without NMI support.
To make it possible to not use a second page, swap the existing
page order so that the IRQ context page is first, and the optional
NMI context page is second. Then, use HAVE_ACPI_APEI_NMI to decide
how many pages are to be allocated.

This commit abstracts MCE calls and provides weak corresponding default
implementation for those architectures which do not need arch specific
actions. Each platform willing to do additional architectural actions
should provides desired function definition. It allows us to avoid wrap
code into #ifdef in generic code and prevent new platform from introducing
dummy stub function too.
Initially, there are two APEI arch-specific calls:
- arch_apei_enable_cmcff()
- arch_apei_report_mem_error()
Both interact with MCE driver for X86 architecture.
