spi_mpc83xx: rework chip selects handling
The main purpose of this patch is to pass 'struct spi_device' to the chip select handling routines. This is needed so that we could implement full-fledged OpenFirmware support for this driver. While at it, also: - Replace two {de,activate}_cs routines by single cs_contol(). - Don't duplicate platform data callbacks in mpc83xx_spi struct.
