msm: thermal: add wakelock for prevent repeat suspend

when device enters suspend after heating,
device will wake up by low threshold. and send notify
to userspace. however, sometimes It enters into suspend
before setting new threshold value by userspace.
It may cause to repeat suspend/resume cycle.
So, add wakelock for preventing it.
