[PATCH v4 13/13] ARM64 / ACPI: Enable ARM64 in Kconfig

[hanjun.guo@linaro.org (Hanjun Guo)]

From: Graeme Gregory <graeme.gregory@linaro.org>

Add Kconfigs to build ACPI on ARM64, and make ACPI available on ARM64.

acpi_idle driver is x86/IA64 dependent now, so make CONFIG_ACPI_PROCESSOR
depend on X86 || IA64, and implement it on ARM64 in the future.
