Blackfin: pm: drop irq save/restore in standby and suspend to mem callback
Since linux-2.6.31, the kernel suspend framework will do disable_irq/enable_irq, so save/restore irq in standby and suspend to mem callback should be dropped. Otherwise the common code notices things are enabled and complains. Signed-off-by: Steven Miao <realmz6@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
