Stefan Ginsberg ae81274578 - Fix a FreeLdr PCI detection bug introduced in revision 10742 5 years ago when PCI detection was added. FindPciBios was setting the HardwareMechanism entry in the PCI_REGISTRY_INFO structure (then called CM_PCI_BUS_DATA) to the wrong register returned from the PCI BIOS: CL instead of AL. CL is the number of the last PCI bus in the system (0 if you only have 1 bus, 1 if you have 2 buses). AL contains bit-fields for PCI characteristics, and HAL checks the 2 first bits to determine the type of the BUS. My VMWare test environment has 2 PCI buses, so the number happened to be correct. This doesn't work if there is only 1 PCI bus, such as in QEMU and Vbox, as we then get an invalid PCI type of 0. Fix this and re-enable the PCI detection in HAL to properly detect the PCI type instead of assuming type 1. ...

- 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.
