[PATCH V2] arm64: kconfig: allow support for memory failure handling

[Tyler Baicar]

From: "Jonathan (Zhixiong) Zhang" <zjzhang at codeaurora.org>

If ACPI_APEI and MEMORY_FAILURE is configured, select
ACPI_APEI_MEMORY_FAILURE. This enables memory failure recovery
when such memory failure is reported through ACPI APEI. APEI
(ACPI Platform Error Interfaces) provides a means for the
platform to convey error information to the kernel.

Declare ARCH_SUPPORTS_MEMORY_FAILURE, as arm64 does support
memory failure recovery attempt.
