clk: Inform the core about consumer devices
We'd like to have a pointer to the device that's consuming a particular
clk in the clk framework so we can link the consumer to the clk provider
with a PM device link. Add a device argument to clk_hw_create_clk() for
this so it can be used in subsequent patches to add and remove the link.
