[PATCH v6 1/4] scmi-cpufreq: Remove deferred probe

[Nicola Mazzucato]

The current implementation still carries a case for a deferred probe, but
in practise this should not happen anymore.

Since the energy model expects to pass the number of OPPs, let us just
move the call dev_pm_opp_get_opp_count closer to EM registration instead.
