Mac OS X (at least with -M mac99) searches for a valid NVRAM partition
of a special Apple type. If it can't find that partition in the first
half of NVRAM, it will look at the second half.
There are a few implications from this. The first is that we need to
split NVRAM into 2 halves - one for Open Firmware use, the other one for
Mac OS X. Without this split Mac OS X will just loop endlessly over the
second half trying to find a partition.
The other implication is that we should provide a specially crafted Mac
OS X compatible NVRAM partition on the second half that Mac OS X can
happily use as it sees fit.

The NVRAM in our Core99 machine really supports 2byte and 4byte accesses
just as well as 1byte accesses. In fact, Mac OS X uses those.
Add support for higher register size granularities.

The macio_nvram_read and macio_nvram_write functions are never called,
just remove them.

After previous Peter patch, they are redundant. This way we don't
assign them except when needed. Once there, there were lots of case
where the ".fields" indentation was wrong:
.fields = (VMStateField []) {
and
.fields = (VMStateField []) {
Change all the combinations to:
.fields = (VMStateField[]){
The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

firmware_abi.h with structs for OpenBIOS landed in hw/sparc/ by mistake
- move it to hw/nvram/ alongside fw_cfg.h. In addition to sparc it's
included from ppc mac_nvram.c and will need to include it from prep.c in
the future.

This patch tackles all files that are compiled once, moving
them to subdirectories of hw/.
