regulator: cpr3-regulator: wait for SPM availability for CPRh controllers

Browse source 
CPRh controllers communicate voltages to the PMIC via the SAW
AVS interface similar to other controllers supporting hardware
closed-loop operation. Ensure the SPM driver has probed and
enabled the SAW AVS system.
