Chen-Yu Tsai f3c5045a95 sunxi: power: axp818: Enable support for ALDOs 
Previously, AXP818 ALDO support was partially added to Kconfig, but
never enabled in the board file, nor properly set or configured in
Kconfig. The boards continue to work because the AXP818 is designed
to pair with the A83T/H8, and the default voltages match the reference
design's requirements.
