IntelFrameworkModule/LegacyBios: Use reserved memory for legacy data

Browse Source 
Certain Legacy USB implementation needs to access legacy data (BDA,
etc.) from SMM environment. While currently it's not allowed to
access BS memory from SMM after EndofDxe, change the legacy data
to use reserved memory type.
