Documentation: power: Describe 'advanced' and 'simple' EM models

The Energy Model (EM) can be registered in two ways:

1) Using a helper function, which under the hood relies on OPP framework
and DT entry in CPU node: 'dynamic-power-coefficient'. This is
a 'simple' EM because it's tied to the math formula:
Power = dynamic-power-coefficient * V^2 * f

2) Using em_dev_register_perf_domain() API function with a driver
custom callback which provides power for each performance state.

This is 'advanced' EM, since it can better reflect real power
measurements for each performance state. It's not limited to any
math formula and can better reflect real physics of the device.

Add description of these two methods to the documentation, so developers
could choose the suitable registration method (option).

Documentation: power: Add description about new callback for EM registration

The Energy Model (EM) registration for CPUs should now be done using
a dedicated callback added recently into CPUFreq framework and drivers.

Commit c17495b01b72 ("cpufreq: Add callback to register with energy model")

The callback guaranties that the EM registration is called at the right
time during driver setup. To avoid mistakes update the documentation
to align with the existing code implementation.
