ARC: [dts] add cpu nodes to ARCHS SMP device tree
Trying to get clock for CPU cores on SMP systems I found that I was only able to get clock for core[0]. That was because only one cpu@0 node was represented in ARC HS device tree and it was impossible to get clock for "non-existing" cores. So as ARC HS may have up to 4 cores we update device tree to match maximum possible cores quantity.
