AGESA: Allow const PcieComplexList for OemCustomize

It's already implemented like this with binaryPI API header.
That implementation is essentially the same with 'const' qualifier
just being ignored in the build process for PI blob.

For open-source AGESA build, work around -Werror=discarded-qualifier
using a simple but ugly cast.
