[hpoussin] 19094: - Add registry entry in HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP for each keyboard class DO

- Add registry entry in HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP for each
keyboard class DO
- Don't search for legacy port drivers in DriverEntry, but in first
AddDevice
- Don't dereference non-referenced objects
