arm64: dts: ti: k3-j722s-evm: Enable analog audio support 

The audio support on J722S-EVM is using TLV320AIC3106[0] codec
connected to McASP1 serializers.

- Add the nodes for sound-card, audio codec and McASP1.
- Add hog for TRC_MUX_SEL to select between McASP and TRACE signals
- Add hogs for GPIO_AUD_RSTn and MCASP1_FET_SEL which is used to
  switch between HDMI audio and codec audio.
- Add pinmux for MCASP1 and AUDIO_EXT_REFCLK1.
