This patch adds the Slave Select locally so that the transfer will
start and complete. The GPIO CS is taken care of earlier in the SPI
framework (spi_set_cs).

This seems like something that other devices might need - it's not the
first time I heard of a device with the data transfer start and chip
select being tied together. Why not make this a generic feature that
the core implements and drivers can enable?

OK. Thanks for the suggestion and review. I'll add a new boolean and device tree binding to the SPI core. Thanks.
