Internal stuff, I will remove it.

Sorry, I realize I have to come back with a bigger patch set.

Timberdale is the MFD driver for the FPGA which among other expose this GPIO device.
This patch set will depend on patches in i2c-ocores and xilinx_spi which I have posted
earlier on the corresponding mailinglists.
Shall I repost those driver changes within this patch set, or can I leave them out?
