This adds the capability to retrieve setup data from the device tree
node. The usage of platform data is still available.
The type of chip_select has been changed from u16 to int so that
of_property_read_u32 does not overwrite other data.

clk_get() no longer needs a character string for associating the right
clock as this is done via the device struct now.

Assuming it fixes access to a device I'm ok with your patch, but I don't
really feel responsible for the driver

In case of error, the function clk_get() returns ERR_PTR()
and never returns NULL pointer. The NULL test in the error
handling should be replaced with IS_ERR().
dpatch engine is used to auto generated this patch.
