[PATCH] add "lspcmcia"

A new "pccardctl ls" provides for extended debugging output related
to the PCMCIA sockets and devices present in the system. Adding one
or two "-v" parameters lets you set how much output you want to have.

Also add a symlink named "lspcmcia" to provide for the same output as
"pccardctl ls".
