Unfortunately, the clock manager's registers are not accessible by the ARM, so we have to request that the firmware modify our clocks for us. This driver only registers the clocks at the point they are requested by a client driver. This is partially to support returning -EPROBE_DEFER when the firmware driver isn't supported yet, but it also avoids issues with disabling "unused" clocks due to them not yet being connected to their consumers in the DT.
