sunxi: axp221: Allow specifying dcdc2 voltage via Kconfig

Browse source 
Allow specifying the axp221 dcdc2 voltage via Kconfig, this is necessary
because on some boards the 1.2V default does not work reliable.

Set the voltage (mV) to program the axp221 dcdc2 at, set to 0 to
disable dcdc2. On A31 boards this is typically used for VDD-GPU,
on A23/A33 for VDD-SYS, this should normally be set to 1.2V.
