Yeah, I'd like to understand why PP_READY isn't getting set; we should
have all of the other pieces ready before we turn on the panel. But,
given that it's really just a sanity check, it probably doesn't make
sense to spin for 5 seconds waiting for a bit to turn on that won't.

I've just removed that bit from the IDLE_ON_MASK and IDLE_ON_VALUE.
