Changes in V9:
 - As per Stephen's comments,
   1. Moved back qup_opp_table from /soc@0/geniqup@9c0000 to /
   2. changed node names to "qup_spi0_cs_gpio: qup-spi0-cs-gpio" beacuse
      node names should have dashes instead of underscores.

Changes in V8:
 - As per Matthias' comments, Added back qup_spiN_cs_gpio nodes in all spi ports

Changes in V7:
 - As per Matthias' comments
   Configuring cs pin with gpio (qup_spiN_cs_gpio) definitions are removed.

 - As per Stephen's comments
   Added qup_opp_table under /soc@0/geniqup@9c0000

Changes in V6:
 - As per Matthias' comments,
   1. Changed convention "clocks" followed by "clock-names"
   2. Moved qup_opp_table from /soc to /

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.

Okay. Shall we remove only "<&qup_spiN_cs_gpio>" in each SPI node?
