This patch implements Allwinner TWI/I2C controller emulation. Only
master-mode functionality is implemented.
The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is
first part enabling the TWI/I2C bus operation.
Since both Allwinner A10 and H3 use the same module, it is added
This patch adds minimal support for AXP-209 PMU.
Most important is chip ID since U-Boot SPL expects version 0x1. Besides
the chip ID register, reset values for two more registers used by A10
