firmware: arm_scpi: add support to populate OPPs and get transition latency
Currently only CPU devices use the transition latency and the OPPs populated in the SCPI driver. scpi-cpufreq has logic to handle these. However, even GPU and other users of SCPI DVFS will need the same logic. In order to avoid duplication, this patch adds support to get DVFS transition latency and add all the OPPs to the device using OPP library helper functions. The helper functions added here can be used for any device whose DVFS are managed by SCPI. Also, we also have incorrect dependency on the cluster identifier for the CPUs. It's fundamentally wrong as the domain id need not match the cluster id. This patch gets rid of that dependency by making use of the clock bindings which are already in place.
