Subject: [PATCH v5 0/3] arm64: dts: ti: k3-j784s4: Add phase tags marking

bootph-all as phase tag was added to dt-schema
(dtschema/schemas/bootph.yaml) to cover U-Boot challenges with DT.
This series adds it to Linux to be aligned with bootloader requirement
for TI K3 J784S4 EVM and TI K3 AM69-SK EVM.

This series will be ported to the k3-j784s4 u-boot support patch
series for syncing, and was requested in its review process:

Bootlog:
https://gist.githubusercontent.com/apurvanandan1997/fe793a7d03e3375af698b20b5bf1c36d/raw/

v5: Changelog:
1) Removed bootph-all from reserved status dts nodes (wkup_uart0)

Link to v4:
https://lore.kernel.org/all/20230811151644.3216621-1-a-nandan@ti.com/

v4: Changelog:
1) Reworked commit title and description

Link to v3:
https://lore.kernel.org/lkml/20230810184302.3097829-1-a-nandan@ti.com/

v3: Changelog:
1) Changed all the bootph-pre-ram to bootph-all, as only
   secure_proxy_mcu and secure_proxy_sa3 are exclusively used by R5 SPL.
   Rest of the nodes are also used by later boot stages.
2) Merged SoC dtsi changes in single patch.
3) Moved cbass_main and cbass_mcu_wkup bootph-all to k3-j784s4.dtsi

Link to v2: 
https://lore.kernel.org/lkml/20230807185645.128751-1-a-nandan@ti.com/#t

v2: Changelog:
1) Added k3-am69-sk.dts bootph-pre-ram patch
2) Added bootph-pre-ram for wkup_pmx0 and ospi0
3) Added bootph-pre-ram for mcu_timer1
