d3504fee73 spi: Use spi_alloc_slave() in each SPI driver 
Rather than each driver having its own way to allocate a SPI slave,
use the new allocation function everywhere. This will make it easier
to extend the interface without breaking drivers.

59d0612252 ColdFire: Queued SPI driver 
This patch adds a driver for Freescale Colfire Queued SPI bus.
Coded to work with 8 bits per transfer to use with SPI flash.
CPOL, CPHA, and CS_ACTIVE_HIGH can be configured.

Tested with MCF5270 which have 4 chip selects.

Activate by #define CONFIG_CF_QSPI in board config.
