firmware: arm_scmi: Specify the performance level when adding an OPP

To enable the performance level to be used for OPPs, let's convert into
using the dev_pm_opp_add_dynamic() API when creating them. This will be
particularly useful for the SCMI performance domain, as shown through
subsequent changes.
