Log:
- Fix broken HalpQueryPciRegistryInfo: If it wasn't for the fact that it queried a
subkey incorrectly ('ConfigurationData' instead of 'Configuration Data')
it was setting up the basic structure correctly but forgot to RETURN IT TO THE CALLER.
- Fixes PCI detection detection as HalpInitializePciStubs no longer has to rely on a
'no info = PCI 1' assumption, making PCI 2 detection possible.
- Add support for querying the CurrentControlSet\Control\PnP\PCI\CardList key and
retrieving the card list entries (not used yet). Also add the related keys to hivesys.inf
so there is something to query.
