Subject: [PATCH] spi: spi-geni-qcom: Use the new method of gpio CS control

Let's set the 'use_gpio_descriptors' field so that we use the new way of
requesting the CS GPIOs in the core. This allows us to avoid having to
configure the CS pins in "output" mode with an 'output-enable' pinctrl
setting.
