clk: fractional-divider: Add hw based registration APIs
Add registration APIs in the clk fractional divider code to return struct clk_hw pointers instead of struct clk pointers. This way we hide the struct clk pointer from providers unless they need to use consumer facing APIs. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
