pcmcia: fix up alignf issues 

- pcmcia_align() used a "start" variable twice. That's obviously a bad
  idea.

- pcmcia_common_resource() needs the current "start" parameter being
  passed, instead of res->start.

- pcmcia_common_resource() doesn't use the size and align parameters,
  so get rid of those.
