Subject[char-misc 3.10] mei: me: clear interrupts on the resume path
Date
We need to clear pending interrupts on the resume
path. This brings the device into defined state
before starting the reset flow

This should solve suspend/resume issues:

mei_me : wait hw ready failed. status = 0x0
mei_me : version message write failed
