[PATCH v2] ARM: dts: renesas: Add boot phase tags marking to Renesas RZ/A1

[Marek Vasut]

bootph-all as phase tag was added to dt-schema (dtschema/schemas/bootph.yaml)
to describe various node usage during boot phases with DT. Add bootph-all for
all nodes that are used in the bootloader on Renesas RZ/A1 SoC.

All SoC require BSC bus, PFC pin control and OSTM0 timer access during all
stages of the boot process, those are marked using bootph-all property, and
so is the SoC bus node which contains the PFC and OSTM IPs.

Each board console UART is also marked as bootph-all to make it available in
all stages of the boot process.
