clk: Add of_clk_hw_register() API for early clk drivers

Browse source

In some circumstances drivers register clks early and don't have access
to a struct device because the device model isn't initialized yet. Add
an API to let drivers register clks associated with a struct device_node
so that these drivers can participate in getting parent clks through DT.
