eth: amd: remove NI6510 support (ni65) 

Looks like all the changes to this driver had been tree-wide
refactoring since git era begun. The driver is using virt_to_bus()
we should make it use more modern DMA APIs but since it's unlikely
to be getting any use these days delete it instead. We can always
revert to bring it back.

/*
* ni6510 (am7990 'lance' chip) driver for Linux-net-3
* BETAcode v0.71 (96/09/29) for 2.0.0 (or later)
* copyrights (c) 1994,1995,1996 by M.Hipp
*
* This driver can handle the old ni6510 board and the newer ni6510
* EtherBlaster. (probably it also works with every full NE2100
* compatible card)
*
* driver probes: io: 0x360,0x300,0x320,0x340 / dma: 3,5,6,7
*
* This is an extension to the Linux operating system, and is covered by the
* same GNU General Public License that covers the Linux-kernel.
*
* comments/bugs/suggestions can be sent to:
* Michael Hipp
* email: hippm@informatik.uni-tuebingen.de
*
* sources:
* some things are from the 'ni6510-packet-driver for dos by Russ Nelson'
* and from the original drivers by D.Becker
*
* known problems:
* - on some PCI boards (including my own) the card/board/ISA-bridge has
* problems with bus master DMA. This results in lotsa overruns.
* It may help to '#define RCV_PARANOIA_CHECK' or try to #undef
* the XMT and RCV_VIA_SKB option .. this reduces driver performance.
* Or just play with your BIOS options to optimize ISA-DMA access.
* Maybe you also wanna play with the LOW_PERFORAMCE and MID_PERFORMANCE
* defines -> please report me your experience then
* - Harald reported for ASUS SP3G mainboards, that you should use
* the 'optimal settings' from the user's manual on page 3-12!
*
* credits:
* thanx to Jason Sullivan for sending me a ni6510 card!
* lot of debug runs with ASUS SP3G Boards (Intel Saturn) by Harald Koenig
*
* simple performance test: (486DX-33/Ni6510-EB receives from 486DX4-100/Ni6510-EB)
* average: FTP -> 8384421 bytes received in 8.5 seconds
* (no RCV_VIA_SKB,no XMT_VIA_SKB,PARANOIA_CHECK,4 XMIT BUFS, 8 RCV_BUFFS)
* peak: FTP -> 8384421 bytes received in 7.5 seconds
* (RCV_VIA_SKB,XMT_VIA_SKB,no PARANOIA_CHECK,1(!) XMIT BUF, 16 RCV BUFFS)
*/
/*
* 99.Jun.8: added support for /proc/net/dev byte count for xosview (HK)
* 96.Sept.29: virt_to_bus stuff added for new memory modell
* 96.April.29: Added Harald Koenig's Patches (MH)
* 96.April.13: enhanced error handling .. more tests (MH)
* 96.April.5/6: a lot of performance tests. Got it stable now (hopefully) (MH)
* 96.April.1: (no joke ;) .. added EtherBlaster and Module support (MH)
* 96.Feb.19: fixed a few bugs .. cleanups .. tested for 1.3.66 (MH)
* hopefully no more 16MB limit
*
* 95.Nov.18: multicast tweaked (AC).
*
* 94.Aug.22: changes in xmit_intr (ack more than one xmitted-packet), ni65_send_packet (p->lock) (MH)
*
* 94.July.16: fixed bugs in recv_skb and skb-alloc stuff (MH)
