sunxi: power: add support for sy8106a driver
SY8106A is a PMIC which is used on the Allwinner H3 Orange Pi Pc and Plus board. The VOUT1_SEL register is implemented to set the default V-CPU voltage to 1200 mV. This driver is required to ensure the SY8106A V-CPU voltage is set to 1200 mV after a software reset. On cold boot the default SY8106A output voltage is selected to be 1200 mV by a pair of resistors on the Orange Pi PC and Plus.
