clk: basic: improve parent_names & return errors
This patch is the basic clk version of 'clk: core: copy parent_names & return error codes'. The registration functions are changed to allow the core code to copy the array of strings and allow platforms to declare those arrays as __initdata. This patch also converts all of the basic clk registration functions to return error codes which better aligns them with the existing clk.h api. Signed-off-by: Mike Turquette <mturquette@linaro.org>
