Sorry to mislead you. I see now why it can't be here. qeniqup has
address cells and size cells not equal to zero, which means that every
child node of qeniqup should have a reg property. So this OPP table
needs to be moved to the root again (ugh).

Please make it "qup_spi0_cs_gpio: qup-spi0-cs-gpio" as node names should
have dashes instead of underscores.
