drivers/intel/fsp2_0: Fix running on x86_64
Add new Kconfig symbols to mark FSP binary as x86_32. Fix the FSP headers and replace void pointers by fixed sized integers depending on the used mode to compile the FSP. This issue has been reported 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. Tested on Intel Skylake. FSP-M no longer returns the error "Invalid Parameter".
