Reserve and ignore the a new module metadata type MDT_PNP_INFO for
associating an optional PNP hint table with this module. In the
future, when these are added, these changes will silently ignore the
new type they would otherwise warn about. It will always be safe to
ignore this data. Get this into the builds today for some future
proofing.
