powerpc: use %*pb[l] to print bitmaps including cpumasks and nodemasks

Browse Source 
printk and friends can now format bitmaps using '%*pb[l]'.  cpumask
and nodemask also provide cpumask_pr_args() and nodemask_pr_args()
respectively which can be used to generate the two printf arguments
necessary to format the specified cpu/nodemask.

* Spurious if (len > 1) test dropped from shared_cpu_map_show().
