Subject: [PATCH v2] PCI: Add information about describing PCI in ACPI

Here's another stab at this writeup.  I'd appreciate any comments!

Changes from v1 to v2:
  - Consumer/Producer is defined for Extended Address Space descriptors;
    should be ignored for QWord/DWord/Word Address Space descriptors
  - New arches may use Extended Address Space descriptors in PNP0A03 for
    bridge registers, including ECAM (if the arch adds support for this)
  - Add more details about MCFG and _CBA (Lv's suggestion)
  - Incorporate Rafael's suggestions
