Subject: [PATCH 4/6] clk: meson: meson8b: add the ddr_pll input for the audio clocks

The two audio muxes cts_amclk_sel and cts_mclk_i958_sel use ddr_pll as
input at index 0. Update the muxes to use clk_parent_data and add
"ddr_pll" as input using clk_parent_data.fw_name because the DDR clock
controller is actually separate from the main clock controller.
