Add Airoha CPU PM Domain support to control frequency and power of CPU present on Airoha EN7581 SoC. Frequency and power can be controlled with the use of the SMC command by passing the performance state. The driver also expose a read-only clock that expose the current CPU frequency with SMC command.
