spi: pxa2xx_spi: Convert to use GPIO descriptors

This converts the PXA2xx SPI driver to use GPIO descriptors
exclusively to retrieve GPIO chip select lines.

The device tree and ACPI paths of the driver already use
descriptors, hence ->use_gpio_descriptors is already set and
this codepath is well tested.

Convert all the PXA boards providing chip select GPIOs as
platform data and drop the old GPIO chipselect handling in
favor of the core managing it exclusively.
