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.
