spi/pl022: Add spi->mode support to AMBA SPI driver
This patch adds spi->mode support for the AMBA pl022 driver and allows spidev to correctly alter SPI modes. Unused fields used in the pl022 header file for the pl022_config_chip have been removed. The ab8500 client driver selects the data transfer size instead of the platform data. For platforms that use the amba pl022 driver, the unused fields in the controller data structure have been removed and the .mode field in the SPI board info structure is used instead.
