[PATCH 3/3] arm64: dts: ti: k3-am625-sk: Add boot phase tags marking

From: Nishanth Menon
Date: Mon Sep 11 2023 - 17:30:31 EST

bootph-all as phase tag was added to dt-schema
(dtschema/schemas/bootph.yaml) to describe various node usage during
boot phases with DT.

Describe the same for am625-sk boot devices.
