sunxi: support the AXP809 PMIC (for A80 platforms)
Implement support for the AXP809 PMIC that is used on A80 platforms
as the primary PMIC and powers most peripherals and the CPUA (Cortex-A7)
cluster. A AXP806 is usually the slave PMIC, which will provide the
power for the CPUB (Cortex-A15) cluster.
The default voltage settings have been chosen to be safe values for a
Optimus, Cubieboard and A80-Q7. These changes are validated against the
A80-Q7 module.
