[PATCH v2] * IntelFsp2Pkg: Improve FSP Python scripts to support 3.x.

["Cheng, Ching JenX" <ching.jenx.cheng@intel.com>]

BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=2041

[PATCH v2] Update commit message for more detail description

When running with Python 3.x and relying on GenCfgOpt.py to
automatically assign UPD offsets,
the script crashed because some float type variable not compatible with
the operations.
Convert those float variable to int to fix these issues.
