PM: EM: update Kconfig description and drop "default n" option

Browse source 
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'.

Several subsystems (thermal and/or the task scheduler for example)
can leverage information about the energy consumed by CPUs to make
smarter decisions. This config option enables the framework from
which subsystems can access the energy models.

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