Subject: [PATCH 02/61] Fix feature mask for IT8792E (IT8733E)
The chip features match those of IT8790E. Most important is the
ADC resolution, which is 12 mV, not 10.9 mV.

Subject: [PATCH 07/61] Separate internal scaling from 12mV ADC
Some chips have internal voltage scaling but 10.9mV ADC,
so we can no longer associate the 12mV ADC with internal scaling
but need a different flag to distinguish scaling support.
Also fix ADC resolution for IT8790E and IT8792E.
