Adapt the functions used to create and write to the RTAS-log partition
to work with any OS-type partition.

The nvram log partition stuff currently in nvram_64.c is really
pseries specific. It isn't actually used on anything else (despite
the fact that we ran the code to setup the partition on anything
except powermac) and the log format is specific to pseries RTAS
implementation. So move it where it belongs

This moves a bunch of definitions out of asm/nvram.h to the files
that use them or just outright remove completely unused stuff.

We leave the partition signatures definitions, they will be useful

nvram_find_partition() has no user. The call site was removed in the
arch/powerpc move, but the function stayed. Remove it.

Remove the reliance on a staticly defined NVRAM size, allowing
platforms to support NVRAMs with sizes differing from the standard.

A fall back value is provided for platforms not supporting this extension.

from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
