pci: missing documentation for dealing with 64 bit config fields

pci spec says what width access to use for 32, 16 and 8
bit fields, but does not explicitly say what to do for
32 bit fields. As we have text that says driver must
treat 64 bit accesses as non-atomic, this seems
to imply driver should always do two 32 bit wide accesses.

Let's make this an explicit requirement, and require
devices to support this.
