arm64: dts: renesas: rz-smarc: Use versa3 clk for audio mclk
Currently audio mclk uses a fixed clk of 11.2896MHz (multiple of 44.1kHz). Replace this fixed clk with the programmable versa3 clk that can provide the clocking to support both 44.1kHz (with a clock of 11.2896MHz) and 48kHz (with a clock of 12.2880MHz), based on audio sampling rate for playback and record.
