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. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
