clk: Add {devm_}clk_hw_{register,unregister}() APIs
We've largely split the clk consumer and provider APIs along struct clk and struct clk_hw, but clk_register() still returns a struct clk pointer for each struct clk_hw that's registered. Eventually we'd like to only allocate struct clks when there's a user, because struct clk is per-user now, so clk_register() needs to change. Let's add new APIs to register struct clk_hws, but this time we'll hide the struct clk from the caller by returning an int error code. Also add an unregistration API that takes the clk_hw structure that was passed to the registration API. This way provider drivers never have to deal with a struct clk pointer unless they're using the clk consumer APIs. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
