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.
