[PATCH] pcmcia/yenta: add support for more TI bridges

[PATCH] pcmcia/yenta: add support for more TI bridges

support some more TI cardbus bridges. most of them are multifunction devices
which adds 1394 controllers, smartcard readers etc. this could also help with
the various problems with the XX21 controllers seen on the linux-pcmcia list.
