[NTOS]: Re-implement IoGetDeviceProperty. Main changes are usage of existing (and new) helper functions for registry/IRP access, much better factored code, correct implementation of DevicePropertyPhysicalDeviceObjectName, fixed implementation of DevicePropertyBootConfigurationTranslated and DevicePropertyBootConfiguration (do not crash the system anymore), and support for more device properties.
[NTOS]: Fix caller of IoGetDeviceProperty in pnpres.c to work with new function behavior (which matches WDK documentation and test cases).
[NTOS]: Implement helper function PnpBusTypeGuidGet, should be used later in other PnP code, but now used only for this patch.
[NTOS]: Implement helper function PnpDetermineResourceListSize, ditto. N.B. Current IopCalculateResourceListSize function is broken and callers should use this one instead.
[NTOS]: Implement helper function PpIrpQueryCapabilities, should be used later in device node code, but now only used for this patch.
[NTOS]: Implement helper function PnpDeviceObjectToDeviceInstance, ditto.
Main purpose of this patch is to unblock the new PCIx driver.
