We used to runtime patch the trap table for srmmu.
With the removal of sun4c support this is no longer required.
With the sun4c trap removed we can remove all the referenced
trap handling which is sun4c specific.
This also allows us to get rid of the nosun4c.c file that
contained only dummy functions/data.

Machines with sun4c support are very rare these days, and noone
is using them for any practical purposes.
The sun4c support has been know broken for quite some time too.
So rather than trying to keep it up-to-date, lets get rid of it.
This allows us to do some very welcome cleanup of sparc32 support.
Updated the former sun4c specifc nmi (which was also used
for sun4m UP) to be a generic UP NMI.

The majority of this patch was created by the following script:
***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***
The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.
