[PATCH 01/26] clk: Add clk_hw_get_num_parents()

[Stephen Boyd <sboyd@codeaurora.org>]

Most provider drivers don't need to deal with struct clk, but
they may want to call __clk_get_num_parents() and so they have to
get the struct clk out of struct clk_hw so they can ask the
framework for the number of parents. Hide this all behind a
clk_hw specific API.
