i2c: Add support for I2C bus on Freescale CPM1/CPM2 controllers
This driver uses the port of 2.4 code from Vitaly Bordug <vitb@kernel.crashing.org> and the actual algorithm used by the i2c driver of the DBox code on cvs.tuxboc.org from Felix Domke (tmbinc@gmx.net) and Gillem (htoa@gmx.net) converted to an of_platform_driver. Tested on CPM1 (MPC823 on dbox2 hardware) and CPM2 (MPC8272). Signed-off-by:Jochen Friedrich <jochen@scram.de> Tested-by:
