[media] ite-cir: make IR receive work after resume

Just recently acquired an Asus Eee Box PC with an onboard IR receiver
driven by ite-cir (ITE8713 sub-variant). Works out of the box with the
ite-cir driver in 2.6.39, but stops working after a suspend/resume
cycle. Its fixed by simply reinitializing registers after resume,
similar to what's done in the nuvoton-cir driver. I've not tested with
any other ITE variant, but code inspection suggests this should be safe
on all variants.
