Move idle_boot_override out of the arch directory to be a single enum
including both platforms values, this will make it rather easier to
avoid ifdefs around which definitions are for which processor in
generally used ACPI code.
IDLE_FORCE_MWAIT for IA64 is not used anywhere, so romove it.
No functional change in this patch.
