spi/dw_spi: enable platform specific chipselect.
The driver core allows for a platform-specific chipselect assert/deassert function, however the chipselect function in the core doesn't take advantage of this fact. This enables the use of a custom function, should it be defined. Signed-off-by: George Shore <george@georgeshore.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
