[RFC PATCH v1 3/3] riscv: dts: starfive: jh7110: bootph-pre-ram hinting needed by boot loader

[E Shattow]

  Add bootph-pre-ram hinting to jh7110.dtsi:
  - CPU interrupt controller(s)
  - timer
  - DRAM memory controller
  - oscillator
  - syscrg clock-controller
  - (optional) dma controller
  - (optional) aoncrg clock-controller

  With this the U-Boot SPL secondary program loader may drop such
  overrides when using dt-rebasing with JH7110 OF_UPSTREAM board targets.
