The AV96 is in fact an assembly of DH Electronics DHCOR SoM on top of an AV96 reference board. Split the DTs to reflect that and make sure to DHCOR SoM can be reused on other boards easily. It is also highly recommended to configure the board for the DHCOM make stm32mp15_dhcom_basic_defconfig make DEVICE_TREE=stm32mp15xx-dhcor-avenger96 as that permits reusing the board code for the DH components, like accessing and reading out the ethernet MAC from EEPROM.
