Testing i2c in 3.6.0-next-20121012 for i.mx233

[Tim michals]

Using the 3.6.0-next-20121012  to test i2c DMA support on a imx233-Olinuxino-micro board.  When using the i2cdetect -r 0 to scan a devices on the i2c bus,  the following message is displayed on the console:

-- [  129.130000] mxs-i2c 80058000.i2c: Failed to get PIO reg. write descriptor.
