ARM: remove ixp23xx and ixp2000 platforms

ixp2xxx platforms have had no real changes since ~2006 and the maintainer
has said on irc that they can be removed:

13:05 < nico> do you still care about ixp2000?
13:22 < lennert> not really, no
13:58 < nico> do you think we could remove it from the kernel tree?
14:01 < lennert> go for it, and remove ixp23xx too while you're at it

Removing will help simplify ARM consolidation in general and PCI re-work
specifically.

Release Notes for Linux on Intel's IXP2000 Network Processor
Maintained by Deepak Saxena <dsaxena@plexity.net>
-------------------------------------------------------------------------
1. Overview
Intel's IXP2000 family of NPUs (IXP2400, IXP2800, IXP2850) is designed
for high-performance network applications such high-availability
telecom systems. In addition to an XScale core, it contains up to 8
"MicroEngines" that run special code, several high-end networking
interfaces (UTOPIA, SPI, etc), a PCI host bridge, one serial port,
flash interface, and some other odds and ends. For more information, see:
http://developer.intel.com
2. Linux Support
Linux currently supports the following features on the IXP2000 NPUs:
- On-chip serial
- PCI
- Flash (MTD/JFFS2)
- I2C through GPIO
- Timers (watchdog, OS)
That is about all we can support under Linux ATM b/c the core networking
components of the chip are accessed via Intel's closed source SDK.
Please contact Intel directly on issues with using those. There is
also a mailing list run by some folks at Princeton University that might
be of help: https://lists.cs.princeton.edu/mailman/listinfo/ixp2xxx
WHATEVER YOU DO, DO NOT POST EMAIL TO THE LINUX-ARM OR LINUX-ARM-KERNEL
MAILING LISTS REGARDING THE INTEL SDK.
3. Supported Platforms
- Intel IXDP2400 Reference Platform
- Intel IXDP2800 Reference Platform
- Intel IXDP2401 Reference Platform
- Intel IXDP2801 Reference Platform
- RadiSys ENP-2611
4. Usage Notes
- The IXP2000 platforms usually have rather complex PCI bus topologies
with large memory space requirements. In addition, b/c of the way the
Intel SDK is designed, devices are enumerated in a very specific
way. B/c of this this, we use "pci=firmware" option in the kernel
command line so that we do not re-enumerate the bus.
- IXDP2x01 systems have variable clock tick rates that we cannot determine
via HW registers. The "ixdp2x01_clk=XXX" cmd line options allow you
to pass the clock rate to the board port.
5. Thanks
The IXP2000 work has been funded by Intel Corp. and MontaVista Software, Inc.
