pcmcia: remove obsolete and wrong comments

What's worse than no comment? A wrong comment.

Several PCMCIA device drivers contained the same comments, which
were based on how the PCMCIA subsystem worked in the old days of 2.4.,
and which were originally part of a "dummy_cs" driver. These comments
no longer matched at all what is happening now, and therefore should
be removed.
