A developer supplied function to perform platform specific operations.
It's a developer supplied function to perform any operations appropriate to a
given platform. It's invoked just before passing control to PEI core by SEC
core. Platform developer may modify the SecCoreData passed to PEI Core.
It returns a platform specific PPI list that platform wishes to pass to PEI core.
The Generic SEC core module will merge this list to join the final list passed to
PEI core.
@param SecCoreData The same parameter as passing to PEI core. It
could be overridden by this function.
@return The platform specific PPI list to be passed to PEI core or
NULL if there is no need of such platform specific PPI list.
