Support for the Timberdale FPGA

To follow is a set of patches implementing some of the peripherals on the Timberdale FPGA. The FPGA can currently be fount on the Russellville board, which is a development board for the Intel Atom CPU to be used for in-vehicle infotainment.

There are some patches previously sent (KS8842 (ethernet), ADV7180 (video decoder) and TSC2003 (touch screen controller)) which are needed to fully use this board.

The drivers has been in the moblin IVI kernel for a while.

Some of the patches implements support for new hardware and some patches existing drives.

Thanks
