clk: make strings in parent name arrays const

The clk functions and structs declare the parent_name arrays as
'const char **parent_names' which means the parent name strings
are const, but the array itself is not. Use
'const char * const * parent_names' instead which also makes
the array const. This allows us to put the parent_name arrays into
the __initconst section.
