Allow a user to override the QM_SMP value giving them the opportunity to
select for themselves the number of CPUs to use in qemu.

On master oe, build a qemuppc64 with systemd as default init, when we
use nfs bootup, the kernel might panic due to missing symbol in dynamic
libraries as below:

One or more of the libraries systemd depends on failed to load due to
unresolved symbols/functions. This was intermittent - with a failure
rate estimated between 5% and 30%.
After checking the code, this issue happens on gcc 12, kirkstone is using
gcc 11 works well, with both using the exact same v5.15.84 kernel commit.
There is a kernel fix from upstream [1], they changed the rsize / wsize
to a multiple of PAGE_SIZE, when we applied this patch, the qemuppc64's
default r/wsize went from 4096 to 524288.But the qemuppc64 doesn't have
its own linux-yocto kernel branch, so apply this change might cause
regression with other platforms which share branch with qemuppc64.
So, we added an extra option for nfs rootfs, and set the qemuppc64 default
r/w size to 524288 to line up with the kernel fix[1].
Yocto did a similar thing in the distant past[2] - prior to boot-arg
adjustments existing - by allowing a Kconfig to set the defaults on
nfsboot, in order to work around hardware limitations.

This feature results in X11 crashes on Qemu since 5.13+ when it was added
disable it therefore for qemuppc64

Move all of the tune files found in conf/machine/include into their
respective architecture directories in that same location. All
references to these will need to be updated. So, change the relevant
ones for this tree in this commit as well.
For the ARM tunes, nest them one further into armv8a, armv8m, etc. and
rename some to make them uniform with the rest of the tunes.
