Some parent clocks of the Exynos5433 CMUs must be always enabled to access any register in the given CMU or devices connected to it. For the time being, until a proper solution based on runtime PM is applied, mark those clocks as critical (instead of ignore unused) to prevent disabling them.

This adds initial support for clocks controlled by the Resource Power Manager (RPM) processor on some Qualcomm SoCs, which use the qcom_smd_rpm driver to communicate with RPM. Such platforms are msm8916, apq8084 and msm8974. The RPM is a dedicated hardware engine for managing the shared SoC resources in order to keep the lowest power profile. It communicates with other hardware subsystems via shared memory and accepts clock requests, aggregates the requests and turns the clocks on/off or scales them on demand.

Currently the RPM/RPM-SMD clock drivers do not register the xo clocks, so we should always add factor clock.
