pci-cardbus adapter

[Pete Popov <ppopov@mvista.com>]

I put a sample config.ops pcmcia config file in my directory and updated
the README with a few sentences about that file. It's meant for
something like a pci-pcmcia/cardbus adapter and I've tested it with a
Ricoh adapter. Others have asked for help in this area in the past, so I
thought I'd shoot an email to the list.
