Use ARRAY_SIZE() instead of manually specifying num_parents. This makes adding/removing entries to/from parent_data easy and errorproof. This conversion fixes an issue present since the first version of this driver. For the gp1_clk_src, gp2_clk_src and gp3_clk_src it was impossible to select sleep_clk as a prent of the clock, since num_parents was limited to 3 rather than 4. Switching to use num_parents automatically makes sleep_clk available for selection.
