Your answer is right here ^ "48038000.mcasp; cannot claim for
4a300000.pruss", you seem to be trying to use the same pru pins as the
hdmi-audio..

see:

https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Disable_on-board_devices

and do:

disable_uboot_overlay_audio=1

Also, for the "pru" only do the "uboot_overlay_pru=" option..

Finally, any pin your define the PRU, make sure to "disable" from
cape-universal in a special node as one example shown here:

https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-SPI0-ADS8688-0A00.dts#L36-L47
