This patch add IRQF_TIMER flag for all Timer interrupts in linux-MIPS,
which will help to not disable the Timer IRQ when suspending to ensure
resuming normally(d6c585a4342a2ff627a29f9aea77c5ed4cd76023) and not
thread them when enabled PREEMPT_RT.
NOTE: Perhaps there are also some board-specific Timer interrupts
missing here!
(This -v1 version Incorporated the feedback from Atsushi Nemoto
<anemo@mba.ocn.ne.jp>.)
