[PATCH] pcmcia: remove dev_list from drivers

The linked list of devices managed by each PCMCIA driver is, in very most
cases, unused. Therefore, remove it from many drivers.

A dev_link_t structure has fields for most things that are needed
to keep track of a socket, but there will usually be some device
specific information that also needs to be kept track of. The
'priv' pointer in a dev_link_t structure can be used to point to
a device-specific private data structure, like this.
A driver needs to provide a dev_node_t structure for each device
on a card. In some cases, there is only one device per card (for
example, ethernet cards, modems). In other cases, there may be
