spi/pxa2xx: embed the ssp_device to platform data
The spi-pxa2xx-pci glue driver had to implement pxa_ssp_request()/free() in order to support the spi-pxa2xx platform driver. Since the ACPI enabled platforms can use the same platform driver we would need to implement pxa_ssp_request()/free() in some central place that can be shared by the ACPI and PCI glue code. Instead of doing that we can make pxa_ssp_request()/free() to be available only when CONFIG_ARCH_PXA is set. On other arches these are being stubbed out in preference to passing the ssp_device from the platform data directly. We also change the SPI bus number to be taken from ssp->port_id instead of platform device id. This way the supporting code that passes the ssp can decide the number (or it can set it to the same as pdev->id).
