MIPS: Hibernation: Remove SMP TLB and cacheflushing code.
We can't perform any flushes on SMP from swsusp_arch_resume because
interrupts are disabled. A cross-CPU flush is unnecessary anyway
because all but the local CPU have already been disabled. A local
flush is not needed either because we didn't change any mappings. So
just delete the code.
