sun6i-a31-apb0-gates supports using clock-indices for holes between individual gates. However, the driver passes the number of gates registered in clk_data->clk_num, which of_clk_src_onecell_get uses to recognize the range of valid indices a consumer can use. This patch makes the driver pass the maximum gate index + 1, so of_clk_src_onecell_get does not complain about indices greater than gates registered. This was tested on the A23 SoC, which has a similar APB0 clock, but has holes for gates to removed IP blocks.
