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.

-   because they generally shouldn't be allocated dynamically.

-   In this case, we also provide a flag to indicate if a device is
