{hw/i2c,docs/system/arm}: Allwinner TWI/I2C Emulation
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.
