powerpc: Linux cannot run with 0 cores
If we configure with CONFIG_SMP=n or set NR_CPUS less than the number of SMT threads we will set the max cores property to 0 in the ibm,client-architecture-support structure. On new versions of firmware that understand this property it obliges and terminates our partition. Use DIV_ROUND_UP so we handle not only the CONFIG_SMP=n case but also the case where NR_CPUS isn't a multiple of the number of SMT threads.
