Fix the FSP headers and replace void pointers by fixed sized integers depending on the used mode to compile the FSP. Change request here:https://github.com/intel/FSP/issues/59 This is necessary to run on x86_64, as pointers have different size. Add preprocessor error to warn that x86_64 FSP isn't supported by the current code.
