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.
