[MinnowBoard] Change I2C clock frequency on MinnowBoardMax

[John Hawley]

Are you not seeing the device at all?  Do you have i2c-dev (usually a
module) loaded?  i2c_bus needs both a bus id (you probably want 7 in
this case), and the clkrate, no idea if the Designware can handle faster.

Is the code for the driver, and there's some Baytrail specific setup
around line 172
