I had completely forgotten about it until I found the patch when I was
sorting these old day unverified patches. At that time, I just sent
DSI patches. I will put it into DSI patches.
Many platforms should work without refgen. Bootloder may have
initialized it and be untouched later? Once there was no refgen
regulator, my sdm845 phone worked.
