[PATCH] x86_64: Clean and enhance up K8 northbridge access code

Browse Source 
- Factor out the duplicated access/cache code into a single file
   * Shared between i386/x86-64.
 - Share flush code between AGP and IOMMU
   * Fix a bug: AGP didn't wait for end of flush before
 - Drop 8 northbridges limit and allocate dynamically
 - Add lock to serialize AGP and IOMMU GART flushes
 - Add PCI ID for next AMD northbridge
 - Random related cleanups

The old K8 NUMA discovery code is unchanged. New systems
should all use SRAT for this.
