clk: bcm: iproc: Migrate to clk_hw based registration and OF APIs

Browse Source 
Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.
