[Patch V1 1/1] \Silicon\Intel\Tools\FitGen: Add extra parameter to the Fit Gen Tool to input the Higher Flash Address

["cbduggap" <chinni.b.duggapu@intel.com>]

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2981

Add extra parameter to the Fit Gen Tool to input the Higher Address.
Default Address should be 4GB and if some one inputs new address,
tool must consume that address instead of Default address (4GB).
