PCI x86: always use conf1 to access config space below 256 bytes
Thanks to Loic Prylli <loic@myri.com>, who originally proposed this idea. Always using legacy configuration mechanism for the legacy config space and extended mechanism (mmconf) for the extended config space is a simple and very logical approach. It's supposed to resolve all known mmconf problems. It still allows per-device quirks (tweaking dev->cfg_size). It also allows to get rid of mmconf fallback code.
