drivers/intel/fsp2_0: Fix running on x86_64

Browse Source 
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".
