This is my attempt to move spi over to using struct gpio_desc. I've stopped at converting struct spi_master to gather some feedback. ep93xx wasn't as hard as I'd expected so I'm pretty happy with those changes. imx on the other hand has an annoying habit of conflating the GPIO and native chip-select so I'm pretty sure that's broken. I've compile tested ep93xx_defconfig and multi_v5_defconfig. Looking ahead to converting struct spi_device there are a number of drivers that re-use cs_gpio to reference the native chip-select so that still poses issues I don't have a plan to solve. Happily most of the changes are deleting code that requests the GPIO since that's now taken care of in core.
