remove the broken SKMC driver 

The SKMC driver has:
- already been marked as BROKEN in 2.6.0 three years ago and
- is still marked as BROKEN.

Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.

But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.

---help---
These are Micro Channel Ethernet adapters. You need to say Y to "MCA
support" in order to use this driver. Supported cards are the SKnet
Junior MC2 and the SKnet MC2(+). The driver automatically
distinguishes between the two cards. Note that using multiple boards
of different type hasn't been tested with this driver. Say Y if you
have one of these Ethernet adapters.
To compile this driver as a module, choose M here and read
<file:Documentation/networking/net-modules.txt>. The module
will be called sk_mca.
