OMAP2 SPI : David Brownells Framework

OMAP2 SPI Driver update:
------------------------

* I have started writing the OMAP2 SPI (Serial Peripheral Interface) driver using David Brownell's Simple SPI Framework.

* I am writing this driver as bit fancy, means "interrupt based transfers" in first phase and later with "dma based transfers".

* If interrupt based transfers works, then my plan is to move this driver using Bitbang interface also, to be useful while testing new OMAP2 series processors and custom boards based on the same too.
