Add support for a Freescale non-CPM SPI controller
This patch adds support for the SPI controller found on Freescale PowerPC
processors such as the MCP834x family. Additionally, a new config option,
CONFIG_HARD_SPI, is added for general purpose SPI controller use.

+ CONFIG_HARD_SPI

+ Enables a hardware SPI driver for general-purpose reads

+ must define a list of chip-select function pointers.
+ Currently supported on some MPC8xxx processors. For an
