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.
