[PATCH] spi: add spi master driver for Freescale MPC83xx SPI controller

Browse source 
This driver supports the SPI controller on the MPC83xx SoC devices from
Freescale.  Note, this driver supports only the simple shift register SPI
controller and not the descriptor based CPM or QUICCEngine SPI controller.
