Hello All,

These three patches enable audio on J784S4-EVM platform.
- First patch adds the McASP nodes.
- Second patch adds the audio_refclk1 node that is required
  to configure the CTRL_MMR register for the external clock
- Third patch enables the analog audio

For audio to work, the ti-dm firmware that should be picked
for uboot is now publically available and will be shortly
merged to the ti-linux-firmware branch:
<https://git.ti.com/cgit/processor-firmware/ti-linux-firmware/tree/ti-dm/j784s4/ipc_echo_testb_mcu1_0_release_strip.xer5f?h=ti-linux-firmware-next>

For testing, ~/.asoundrc file was created in root partition
which can be seen in the test logs:
