This commit extends the existing Vybrid I2C support to cover buses i2c1,
i2c2, and i2c3. Based in (very) large part on an initial patch by
Stefan Agner that was just lacking a couple of DMA assignments.

Thx Cory for picking that up.
So with that patch we use the second Mux of DMA0 the first time. Another
option would have been to use the first Mux of DMA1, however I think its
better to leave DMA1 for dedicated purposes or the secondary Cortex-M4
core... If a board needs different configuration, one would also have
the option to overwrite the properties.
