[PATCH] SPI: add PXA2xx SSP SPI Driver

Browse Source 
This driver turns a PXA2xx synchronous serial port (SSP) into a SPI master
controller (see Documentation/spi/spi_summary).  The driver has the following
features:

- Support for any PXA2xx SSP
- SSP PIO and SSP DMA data transfers.
- External and Internal (SSPFRM) chip selects.
- Per slave device (chip) configuration.
- Full suspend, freeze, resume support.

This enables using a PXA2xx SSP port as a SPI master controller.
The driver can be configured to use any SSP port and additional
documentation can be found a Documentation/spi/pxa2xx.
