ARM: dts: renesas: r7s72100: Add boot phase tags 

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 SoCs.

All SoCs 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.
