A new shift mode was introduced since ar934x which has a way better performance than current bitbang driver and can handle higher spi clock properly. This commit adds a new driver to make use of this new feature. This new driver has chipselect properly configured and we don't need cs-gpios hack in dts anymore. Remove them.
