Yes, that's correct, I have already confirmed from FW team that this 
idle check is always enabled in FW now.

so driver doesn't have to set itexplicitly, that's why it works for you 
on 8250 I believe. So removing this setting seems fine.

My only concern is that why we see a crash when setting it on AR50LT.
