clk: qcom: common: Add support for power-domain attachment 



Right now we support one power-domain per clock controller.
These single power-domains are switched on by the driver platform logic.

However when we have multiple power-domains attached to a clock-controller
that list of power-domains must be handled outside of driver platform
logic.

Use devm_pm_domain_attach_list() to automatically hook the list of given
power-domains in the dtsi for the clock-controller driver.
