The MPM driver now supports two ways to handle sending the RPM notification, either in the genPD's power_off callback as power domain provider, or within the CPU_PM notification framework. Removing #power-domain-cells instructs MPM driver to follow the latter path, which as explained in cover letter would help avoid probe dependencies. Thanks, Sneh
