[fireball] 30703: - Remove CmiInitHives. - Enable parallel hive loading, this speeds up boot by loading the registry in 6 threads instead of just one (once we start having large registries and MP support this will be more evident). - Added some little hacks to make this work for now. - Fix a memory leak in CmInit1. - Add hardware hive to machine hive list so it can be properly loaded after.

Log:
- Remove CmiInitHives.
- Enable parallel hive loading, this speeds up boot by loading the registry in 6 threads
instead of just one (once we start having large registries and MP support this will be
more evident).
- Added some little hacks to make this work for now.
- Fix a memory leak in CmInit1.
- Add hardware hive to machine hive list so it can be properly loaded after.
