drivers/net: delete the really obsolete 8390 based 10Mbit ISA drivers

This is an area I know all too well, after being author of several 8390
drivers, and maintainer of all 8390 drivers during a large part of their
active lifecycle.

To that end, I can say this with a reasonable degree of confidence.
The drivers deleted here represent the earliest (as in early 1990)
hardware and/or rare hardware.  The remaining hardware not deleted
here is the more modern/sane of the lot, with ISA-PnP and jumperless
"soft configuration" like the wd and smc cards had.

The original ne2000 driver (ne.c) gets a pass at this time since
AT/LANTIC based cards that could be both ne2000 or wd-like (with
shared memory) and with jumperless configuration were made in the
mid to late 1990's, and performed reasonably well for their era.

-
-	The E2100 series ethercard is a fairly generic shared memory 8390
-	implementation.  The only unusual aspect is the way the shared memory
-	registers are set: first you do an inb() in what is normally the
-	station address region, and the low three bits of next outb() *address*
-	is used	as the write value for that register.  Either someone wasn't
-	too used to dem bit en bites, or they were trying to obfuscate the
-	programming interface.
-
-	There is an additional complication when setting the window on the packet
-	buffer.  You must first do a read into the packet buffer region with the
-	low 8 address bits the address setting the page for the start of the packet
-	buffer window, and then do the above operation.  See mem_on() for details.
-
-	One bug on the chip is that even a hard reset won't disable the memory
-	window, usually resulting in a hung machine if mem_off() isn't called.
-	If this happens, you must power down the machine for about 30 seconds.
