Michal Meloun 93a065e749 Remake support for SMP kernel on UP cpu:
- Use new option SMP_ON_UP instead of (mis)using specific CPU type.
   By this, any SMP kernel can be compiled with SMP_ON_UP support.
 - Enable runtime detection of CPU multiprocessor extensions only
   if SMP_ON_UP option is used. In other cases (pure SMP or UP),
   statically compile only required variant.
 - Don't leak multiprocessor instructions to UP kernel.
 - Correctly handle data cache write back to point of unification.
   DCCMVAU is supported on all armv7 cpus.
 - For SMP_ON_UP kernels, detect proper TTB flags on runtime.
