[Linux-ia64] Cleanup include/asm-ia64/offsets.h

include/asm-ia64/offsets.h is causing problems for source control
systems and patches.  Because it is shipped as part of the ia64 tree
and then overwritten wth values that are based on the local config it
generates spurious changes.

There is also the problem of when offsets.h gets updated.  At the
moment it only gets updated by make dep so changes to structures or
config options which affect the offsets are not automatically detected.
Change a config option, forget to run make dep and you get an
inconsistent kernel.

As part of my makefile rewrite for 2.5 I am cleaning up problems like
this.  The patch below deletes include/asm-ia64/offsets.h from the
shipped tree, restricts its use to assembler code only and makes sure
that assembler code always gets the latest offset values.  C code is
not a problem, the dependency system handles structure and config
changes for C code.

If you have a "don't diff" list, add include/asm-ia64/offsets.h,
include/asm/offsets.h and arch/ia64/tools/offsets.h to that list after
applying this patch.

Against 2.4.3-ia64-010405.
