examples/vm_power_manager: add per-core turbo
Add extra commands to command line to allow enable/disable of per-core turbo. When a core has turbo enabled, calling for max frequency will allow it to go to a turbo frequency (P0n). When a core has turbo disabled, calling for max frequency will allow it to go to the maximum non-turbo frequency (P1), but not beyond. Signed-off-by: David Hunt <david.hunt@intel.com>
