Subject: [PATCH 1/2] 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'.

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

Applied along with the [2/2[ as 5.12 material, thanks!
