Hello,

This is third revision of the driver. Thanks to Martin Guy who tested and
reviewed the code.

Changes since v2:
	- corrected spi clock rate calculation
	- interrupt handling is now more efficient
	- driver now supports polling mode as well, this can be selected with
	  'transfer_method' module parameter.
	- controller is disabled in probe function
	- some cosmetic changes

I have been testing this on my TS-7260 board (ep9302 based) with mmc_spi and
at25 drivers.

Note that patch 2/2 depends on patch that is already in Russell's patch
tracking system:

Thanks,
MW
