Add Kconfigs to build ACPI on ARM64, and make ACPI runable on ARM64.
acpi_idle driver is x86/IA64 dependent now, so make CONFIG_ACPI_PROCESSOR
depends on X86 || IA64, and implement it on ARM in the furture.
In order to make arm-core.c can both run on ARM and ARM64, introduce
CONFIG_ACPI_ARM to support it.

Should only be ARM64 here with the current files in this series, I think
this is causing others confusion looking for arm 32bit support in patches
where there is none yet!
ah, yes, my bad, will update it in next version.
Thanks
