staging: remove hp100 driver 

It's old, obsolete, and no one wants to take care of it anymore.

It's been in staging for 5 months with no one paying attention to it, so
let's just delete it for now.

If someone has this hardware, and wants the driver back, the deletion
can be easily reverted.

If you have a network (Ethernet) card belonging to this class, say Y.
Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about HP cards. If you say Y, you will be asked for

To compile this driver as a module, choose M here. The module
will be called hp100.

** hp100.c
** HP CASCADE Architecture Driver for 100VG-AnyLan Network Adapters
**
** $Id: hp100.c,v 1.58 2001/09/24 18:03:01 perex Exp perex $
**
** Based on the HP100 driver written by Jaroslav Kysela <perex@jcu.cz>
** Extended for new busmaster capable chipsets by
** Siegfried "Frieder" Loeffler (dg1sek) <floeff@mathematik.uni-stuttgart.de>
**
** Maintained by: Jaroslav Kysela <perex@perex.cz>
**
** This driver has only been tested with
** -- HP J2585B 10/100 Mbit/s PCI Busmaster
** -- HP J2585A 10/100 Mbit/s PCI
** -- HP J2970A 10 Mbit/s PCI Combo 10base-T/BNC
** -- HP J2973A 10 Mbit/s PCI 10base-T
** -- HP J2573 10/100 ISA
** -- Compex ReadyLink ENET100-VG4 10/100 Mbit/s PCI / EISA
** -- Compex FreedomLine 100/VG 10/100 Mbit/s ISA / EISA / PCI
**
** but it should also work with the other CASCADE based adapters.
**
** TODO:
** - J2573 seems to hang sometimes when in shared memory mode.
** - Mode for Priority TX
** - Check PCI registers, performance might be improved?
** - To reduce interrupt load in busmaster, one could switch off
** the interrupts that are used to refill the queues whenever the
** queues are filled up to more than a certain threshold.
** - some updates for EISA version of card
**
**
**
** 1.57c -> 1.58
** - used indent to change coding-style
** - added KTI DP-200 EISA ID
** - ioremap is also used for low (<1MB) memory (multi-architecture support)
**
** 1.57b -> 1.57c - Arnaldo Carvalho de Melo <acme@conectiva.com.br>
** - release resources on failure in init_module
**
** 1.57 -> 1.57b - Jean II
** - fix spinlocks, SMP is now working !
**
** 1.56 -> 1.57
** - updates for new PCI interface for 2.1 kernels
**
** 1.55 -> 1.56
** - removed printk in misc. interrupt and update statistics to allow
** monitoring of card status
** - timing changes in xmit routines, relogin to 100VG hub added when
** driver does reset
** - included fix for Compex FreedomLine PCI adapter
**
** 1.54 -> 1.55
** - fixed bad initialization in init_module
** - added Compex FreedomLine adapter
** - some fixes in card initialization
**
** 1.53 -> 1.54
** - added hardware multicast filter support (doesn't work)
** - little changes in hp100_sense_lan routine
** - added support for Coax and AUI (J2970)
** - fix for multiple cards and hp100_mode parameter (insmod)
** - fix for shared IRQ
**
** 1.52 -> 1.53
** - fixed bug in multicast support
**
