x86, acpi, idle: Restructure the mwait idle routines
People seem to delight in writing wrong and broken mwait idle routines; collapse the lot. This leaves mwait_play_dead() the sole remaining user of __mwait() and new __mwait() users are probably doing it wrong. Also remove __sti_mwait() as its unused.
