[PATCH] 2/8 Move NUMA-Q support into subarch

[PATCH] 2/8 Move NUMA-Q support into subarch

[Martin J. Bligh]

This patch adds a shell of a NUMA-Q subarch directory, and copies
mach-default/mach_apic.h into it. I then edited the default version
to remove the NUMA-Q stuff, and the NUMA-Q version to remove the
default stuff.
