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.
