pcmcia: dev_node removal (write-only drivers) 

dev_node_t was only used to transport some minor/major numbers
from the PCMCIA device drivers to deprecated userspace helpers.
However, only a few drivers made use of it, and the userspace
helpers are deprecated anyways. Therefore, get rid of dev_node_t .

As a first step, remove any usage of dev_node_t from drivers which
only wrote to this typedef/struct, but did not make use of it.

A linked list of "instances" of the atmelnet device. Each actual
PCMCIA card corresponds to one device instance, and is described

You may not want to use a linked list for this -- for example, the
memory card driver uses an array of struct pcmcia_device pointers, where minor
device numbers are used to derive the corresponding array index.
*/
/*
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
many actual or logical devices (SCSI adapters, memory cards with
multiple partitions). The dev_node_t structures need to be kept
in a linked list starting at the 'dev' field of a struct pcmcia_device
structure. We allocate them in the card's private data structure,
because they generally shouldn't be allocated dynamically.
In this case, we also provide a flag to indicate if a device is
"stopped" due to a power management event, or card ejection. The
device IO routines can use a flag like this to throttle IO to a
card that is not ready to accept it.
