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 for both boards. Docs are also updated for Cubieboard and Orangepi-PC board to indicate I2C availability.
