net/wan: dscc4: remove broken dscc4 driver

Using static analysis, I discovered that the "dpriv->pci_priv->pdev"
pointer is always NULL.  This pointer was supposed to be initialized
during probe and is essential for the driver to work.  It would be easy
to add a "ppriv->pdev = pdev;" to dscc4_found1() but this driver has
been broken since before we started using git and no one has complained
so probably we should just remove it.

Driver for Etinc PCISYNC boards based on the Infineon (ex. Siemens)

This is supposed to work with the four port card. Take a look at
