drivers/net: delete all code/drivers depending on CONFIG_MCA

The support for CONFIG_MCA is being removed, since the 20
year old hardware simply isn't capable of meeting today's
software demands on CPU and memory resources.

This commit removes any MCA specific net drivers, and removes
any MCA specific probe/support code from drivers that were
doing a dual ISA/MCA role.

+    Support for MCA EtherWORKS cards added 11-3-98. (MCA since deleted)
     Verified to work with up to 2 DE212 cards in a system (although not
       fully stress-tested).
 
-    Currently known bugs/limitations:
-
-    Note:  with the MCA stuff as a module, it trusts the MCA configuration,
-           not the command line for IRQ and memory address.  You can
-           specify them if you want, but it will throw your values out.
-           You still have to pass the IO address it was configured as
-           though.
