Now that we have 4xx platform directory we can move the 4xx machine
check handler in there. Again we drop get_mc_reason() and replace it
with regs->dsisr directly (which is actually SPRN_ESR).

We have a lot of code in sysdev for supporting 4xx, ie. either 40x or
44x. Instead it would be cleaner if it was all in platforms/4xx.
This is slightly odd in that we don't actually define any machines in
the 4xx platform, as is usual for a platform directory. But still it
seems like a better result to have all this related code in a directory
by itself.

4xx is a bit of a misnomer for certain things, as they really apply to PowerPC
40x only. Rename some of the files to clean this up.

This fixes up a variety of minor problems in compiling with ARCH=ppc
arising from using the merged versions of various header files.
A lot of the changes are just adding #include <asm/machdep.h> to
files that use ppc_md or smp_ops_t.
This also arranges for us to use semaphore.c, vecemu.c, vector.S and
fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc.
