I think we still want this for all SPI ports, which existed in previous
versions:

			qup_spi0_cs_gpio: qup-spi0-cs-gpio {

				function = "gpio";
			};

It just shouldn't be selected together with 'qup_spiN_cs'.

Maybe a follow up patch would be good enough, so:

ok.shall we add qup_spiN_cs_gpio for all spi ports
