[dpdk-dev] examples/power: allow use of more than 64 cores

[David Hunt <david.hunt@intel.com>]

vm_power_manager has up to now been limited to 64-cores because of the
extensive use of uint64 type for bitmasks. This patch set converts those
uint64s to character arrays, and increases the limit of cores from 64 to
256, and allowing users to increase this by increasing the #define.

First of all we convert all the relevant uint64_t's to char arrays. Then
we remove the unneeded mask functions that were limited to 64 cores. Also
extend the guest functionality and finally rause the number of supported
cores to something more sensible, i.e. 256.

[3/4] examples/power: allow vms to use lcores over 63
[4/4] examples/power: increase MAX_CPUS to 256
