ARC: Allow SMP kernel to build/boot on UP-only infrastructure
In light of recent SNAFU with SMP build, allow simple platform to build
as SMP but run UP.
* Remove the dependence on simulation SMP extension to enable quick
build/test iterations of SMP kernel.
* In absence of platform SMP registration, prevent the NULL smp feature
name from borkign the system
