sunxi: Add i2c support 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.

sunxi: Complete i2c support for each supported platform Sunxi platforms come with at least 3 TWI (I2C) controllers and some platforms even have up to 5. This adds support for every controller on each supported platform, which is especially useful when using expansion ports on single-board- computers.

i2c: mvtwsi: Support for up to 4 different controllers Orion5x, Kirkwood and Armada XP platforms come with a single TWSI (I2C) MVTWSI controller. However, other platforms using MVTWSI may come with more: this is the case on Allwinner (sunxi) platforms, where up to 4 controllers can be found on the same chip.
