sunxi: power: Make all voltages configurable through Kconfig

On boards with axp221/223 pmic-s we already allow configuring most
voltages. Make the Kconfig options for these also apply to boards with
axp152 / axp209 pmic-s and extend them to configure all voltages.

The Kconfig defaults are chosen so that this commit does not introduce any
functional changes.
