staging: net: remove pc300 driver 

To quote the TODO from staging/net/:

  PC300:

  The driver is very broken and cannot work with the current TTY
  layer. It is inevitable to convert it to the new TTY API. If no
  one steps in to adopt the driver, it will be removed in the 3.7
  release.

Nothing has changed since more than _one_ year on this driver, thus
just remove it since we already moved past 3.7. If somebody steps
up and does a whole rework, he/she, of course, is free to resubmit
it. Since this is the only one in the net directory, we can remove
it as well.

---help---
This driver is broken because of struct tty_driver change.
Driver for the Cyclades-PC300 synchronous communication boards.
These boards provide synchronous serial interfaces to your
Linux box (interfaces currently available are RS-232/V.35, X.21 and
T1/E1). If you wish to support Multilink PPP, please select the
option later and read the file README.mlppp provided by PC300
package.
To compile this as a module, choose M here: the module
will be called pc300.
If unsure, say N.
