[dpdk-dev] [PATCH v2 4/4] examples/power: increase max cores to 256

Increase the number of addressable cores from 64 to 256. Also remove the
warning that incresing this number beyond 64 will cause problems (because
of the previous use of uint64_t masks). Now this number can be increased
significantly without causing problems.
