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.

The intent is to enable the use of different models of FORE adapters at the

same time, by hosts that have several bus interfaces (such as PCI+SBUS,

PCI+MCA or PCI+EISA).

or PCI+EISA).



Only PCI and SBUS devices are currently supported by the driver, but support

for other bus interfaces such as EISA should not be too hard to add (this may

be more tricky for the MCA bus, though, as FORE made some MCA-specific

modifications to the adapter's AALI interface).
