[PATCH 6/6] power: pmic: sunxi: add AXP707 support

[Andre Przywara]

The X-Powers AXP707 is a PMIC with some buck converters and a larger
number of LDOs, alongside some charging and USB circuitry.

Add the descriptions for the five DC/DC regulators that we will need,
and enable that when CONFIG_AXP707_POWER is enabled. We won't need DCDC2
till DCDC4, but by using the position in the array for the index we keep
the code cleaner.
