drivers/net: delete Racal Interlan ISA ni52 (i825xx) driver

Like the other drivers that were in the ISA i825xx family, the ni52
was rather rare, not widely used, and hence perhaps not as reliable
as the more mainstream ISA drivers that were heavily used.  Given
that, it is chosen for retirement at this time as well.

- *    [feel free to mail ....]
- *
- * when using as module: (no autoprobing!)
- *   run with e.g:
- *       insmod ni52.o io=0x360 irq=9 memstart=0xd0000 memend=0xd4000
- *
- * CAN YOU PLEASE REPORT ME YOUR PERFORMANCE EXPERIENCES !!.
- *
- * If you find a bug, please report me:
- *   The kernel panic output and any kmsg from the ni52 driver
- *   the ni5210-driver-version and the linux-kernel version
- *   how many shared memory (memsize) on the netcard,
- *   bootprom: yes/no, base_addr, mem_start
- *   maybe the ni5210-card revision and the i82586 version
- *
- * autoprobe for: base_addr: 0x300,0x280,0x360,0x320,0x340
- *                mem_start: 0xd0000,0xd2000,0xc8000,0xca000,0xd4000,0xd6000,

- *
- * sources:
- *   skeleton.c from Donald Becker
- *
- * I have also done a look in the following sources: (mail me if you need them)
- *   crynwr-packet-driver by Russ Nelson
- *   Garret A. Wollman's (fourth) i82586-driver for BSD
- *   (before getting an i82596 (yes 596 not 586) manual, the existing drivers
- *    helped me a lot to understand this tricky chip.)
- *
- * Known Problems:
- *   The internal sysbus seems to be slow. So we often lose packets because of
- *   overruns while receiving from a fast remote host.
- *   This can slow down TCP connections. Maybe the newer ni5210 cards are
- *   better. My experience is, that if a machine sends with more than about
- *   500-600K/s the fifo/sysbus overflows.
- *
- * IMPORTANT NOTE:
- *   On fast networks, it's a (very) good idea to have 16K shared memory. With
- *   8K, we can store only 4 receive frames, so it can (easily) happen that a
- *   remote machine 'overruns' our system.
- *
- * Known i82586/card problems (I'm sure, there are many more!):
- *   Running the NOP-mode, the i82586 sometimes seems to forget to report
- *   every xmit-interrupt until we restart the CU.
- *   Another MAJOR bug is, that the RU sometimes seems to ignore the EL-Bit
- *   in the RBD-Struct which indicates an end of the RBD queue.
- *   Instead, the RU fetches another (randomly selected and
- *   usually used) RBD and begins to fill it. (Maybe, this happens only if
- *   the last buffer from the previous RFD fits exact into the queue and
- *   the next RFD can't fetch an initial RBD. Anyone knows more? )
- *
- * results from ftp performance tests with Linux 1.2.5
- *   send and receive about 350-400 KByte/s (peak up to 460 kbytes/s)
- *   sending in NOP-mode: peak performance up to 530K/s (but better don't
- *   run this mode)
