PM: EM: update Kconfig description and drop "default n" option
Energy Model supports now other devices like GPUs, DSPs, not only CPUs. Thus, update the description in the config option. Remove also unneeded "default n". If the "default" line is removed, it defaults to 'n'. Signed-off-by: Lukasz Luba <lukasz.luba@arm.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Several subsystems (thermal and/or the task scheduler for example)

The exact usage of the energy model is subsystem-dependent.
