- Actually it seems MmGetPhysicalMemoryRanges uses the MmPhysicalMemoryBlock, so go ahead and implement that function.

Browse source 
- Thanks to Matthieu Suiche (http://www.msuiche.net/2008/09/17/retrieving-mmphysicalmemoryblock-regardless-of-the-nt-version/).
  - Move physical.c into ARM3 and call it dynamic.c since these functions are for Dynamic Memory (Hotplug) for Server 2003.
  - Remove the old copyright header, as copy-pasting 5 DDK function definitions and rewriting them to say UNIMPLEMENTED isn't much of a copyright.
