soc: qcom: rpmpd: Add parent PD support

Browse source

In some cases (like with the GPU core clock on GMU-less SoCs) it's
required that we scale more than one voltage domain. This can be achieved
by linking them in a parent-child relationship. Add support for specifying
a parent PD, similarly to what has been done in the RPMhPD driver.
