[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.
