[PATCH][VTD] pci mmcfg patch for x86-64 - version 2
Fixes made in version 2:
1) Use PML4[257] for ioremap of PCI mmcfg. As full 16-bit segment support would require 44-bits. Since each slot only has 39-bits, we support 2048 PCI segments for now. This can be easily expanded if deemed necessary in the future.
2) Integrated PCI mmcfg access with existing PCI config interface for x86_64. Use MMCFG interface if offset is greater than 256.
