Subject: [PATCH 1/2] arm64: dts: ti: k3-am65: add boot phase tags

The 'bootph-all' tag was added to the dt-schema to describe the various
nodes used during the different phases of bootup with DT. Add the
bootph-all tag to all required nodes for all AM65x platforms.

Mark the mailbox and ring accelerators needed to communicate the with
various vendor firmware and the power, clock and reset nodes along with
the MMR for the chip-id to facilitate detecting the SoC and which
silicon version during the early stages of bootup with 'bootph-all' as
they are used during all phases of bootup
