sunxi: power: Change A23/A33 VDD-SYS default from 1.2V to 1.1V
Change the axp223 dcdc2 / VDD-SYS default from 1.2V to 1.1V, 1.1V is the
value recommended by Allwinner and is what most fex files specify.
This has been tested on a number of A23/A33 tablets including on an
A23 Ippo-q8h-v1.2 PCB tablet which has a fex file which specifies 1.2V
(which is where our original 1.2V default comes from).
