SB800: Add IMC ROM and fan control.
Add configuration for AMD's IMC ROM and fan registers for cimx/sb800 platforms. - Allows user to add the IMC rom to the build and to configure the location of the "signature" between the allowed positions. - Allows for no fan control, manual setup of SB800 Fan registers, or setup of the IMC fan configuration registers. - Register configuration is done through devicetree.cb. No files need to be added for new platform configuration. - Initial setup is for Persimmon, but may be extended to any cimx/sb800 platform.
