From: "Chasel, Chiu" <chasel.c...@intel.com>
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1716
In API mode FSP wrapper will perform some post
FSP-S process but such process was skipped in Dispatch
mode which may impact some of boot loaders.
To align behavior between API and Dispatch, an
End-of-Pei callback is introduced to perform same process
in Dispatch mode.
Test: Verified on internal platform and both
FSP API and Dispatch modes booted successfully.
