Subject: [PATCH v1 1/3] arm64: dts: ti: var-som-am62p: Refactor IPC configuration into common dtsi

Update the VAR-SOM-AM62P dtsi to align with the refactor introduced by
k3-am62p-ti-ipc-firmware.dtsi common file, allowing to remove the IPC
nodes from the board file including the new common dtsi.

No functional changes intended.
