spi: fsl: Fix GPIO descriptor support
[ Upstream commit f106904968e2a075e64653b9b79dda9f0f070ab5 ]
This makes the driver actually support looking up GPIO
descriptor. A coding mistake in the initial descriptor
support patch was that it was failing to turn on the very
feature it was implementing. Mea culpa.
