This driver has a bunch of custom oldstyle GPIO number-passing fields and a custom set-up callback. The good thing is: nothing in the kernel is using it. Convert the driver to use GPIO descriptors with a SPI_MASTER_GPIO_SS flag so that the local CS callback also get invoked as the hardware needs this. New users of this driver can provide GPIO descriptor tables like the other converted drivers.
