sh: clkfwk: bugfix: sh_clk_div_enable() care sh_clk_div_set_rate() if div6
764f4e4e33d18cde4dcaf8a0d860b749c6d6d08b (sh: clkfwk: Use shared sh_clk_div_enable/disable()) shared enable/disable funcions for div4/div6. But new sh_clk_div_enable() didn't care sh_clk_div_set_rate() which is required on div6 clock. This patch fixes it.
