This should only have qup_spi0_data_clk and qup_spi0_cs, not
qup_spi0_cs_gpio. Both qup controlled and gpio controlled options are
provided in case a board wants to use the qup version of chipselect, but
having them both used by default leads to conflicts and confusion. This
same comment applies to all spi pinctrl properties in this file. Please
keep the cs_gpio variants though so that boards can use them if they
want. They will be unused, but that's OK.
