[PATCH 2/2] spi: spi-mem: fallback to using transfers when CS gpios are used

[Chris Packham <chris.packham@xxxxxxxxxxxxxxxxxxx>]

Devices with chip selects driven via GPIO are not compatible with the
spi-mem operations. Fallback to using standard spi transfers when the
device is connected with a gpio CS.
