[ARM] 4731/1: S3C2412: Check for incomplete sleep

Browse source 
Check if the sleep command returns due to a pending interrupt
in the standby unit. If this happens, try and ack the IRQ
before re-trying the resume.

It is currently unclear whether the resume can be backed out
of at this stage as this could cause a problem with level
based interrupts.
