[PATCH V2 0/6 ] IMX i2c driver update for the PPC 85xx

[Renaud Barbier]

This patch set prepares the PPC 85xx SOC to use the IMX i2c driver and updates
the driver with specific clock settings. The driver name is renamed "i2c-fsl".
The patch also introduces a function returning the system clock to calculate
the i2c frequency bus divider. Finally, the P2020RDB board support is updated
to test the driver on 8-bit and 16-bit I2C devices.

This patch has NOT been tested on a IMX board.
