Add support for the i2c controller found on all Allwinner sunxi SoCs,
this is the same controller as found on the Marvell orion5x and kirkwood
SoC families, with a slightly different register layout, so this patch uses
the existing mvtwsi code.

NACK. Goal is to get rid of HARD_I2C define ... please convert this
driver to fit with CONFIG_SYS_I2C framework.
A fast look in this driver, this should not to be to hard, as this
driver does not support multi busses...
A good example for porting a i2c driver with no multibus support is:
