[S390] Remove Kerntypes leftovers

Remove last traces of our kerntypes patch which was always an addon
patch which never got upstream. Somehow a few bits got upstream
anyway.
Since kerntypes aren't used anymore and lcrash isn't maintained (for
s390 at least) remove the last traces of kerntypes that somehow went
upstream. Also remove the documentation that mentions lcrash.

Dumptool & Lcrash ( lkcd )
==========================
Michael Holzheu & others here at IBM have a fairly mature port of
SGI's lcrash tool which allows one to look at kernel structures in a
running kernel.
It also complements a tool called dumptool which dumps all the kernel's
memory pages & registers to either a tape or a disk.
This can be used by tech support or an ambitious end user do
post mortem debugging of a machine like gdb core dumps.
Going into how to use this tool in detail will be explained
in other documentation supplied by IBM with the patches & the
lcrash homepage http://oss.sgi.com/projects/lkcd/ & the lcrash manpage.
How they work
-------------
Lcrash is a perfectly normal program,however, it requires 2
additional files, Kerntypes which is built using a patch to the
linux kernel sources in the linux root directory & the System.map.
Kerntypes is an objectfile whose sole purpose in life
is to provide stabs debug info to lcrash, to do this
Kerntypes is built from kerntypes.c which just includes the most commonly
referenced header files used when debugging, lcrash can then read the
.stabs section of this file.
Debugging a live system it uses /dev/mem
alternatively for post mortem debugging it uses the data
collected by dumptool.
SysRq
=====
This is now supported by linux for s/390 & z/Architecture.
