[PATCH v2 2/4] ntoskrnl.exe: Implement loading plug and play devices

[Aric Stewart]

v2: No longer maintaining a device store
    Suggestions from Sebastian Lackner

We are not handling installing drivers just yet, so we just make use
of the critical device store. These are drivers that, on Windows, are
automatically loaded on boot every time.  This database is maintained
in [CurrentControlSet/Control/CriticalDeviceDatabase] The keys in this
registry key represent a HardwareID that match a device. We query the
IDs from the bus device’s BusQueryHardwareIDs and if we find a match
(from most specific to most general) we look at that registry key. The
CriticalDeviceDatabase entry specify a [Service] value representing
the driver.
