Subject: [PATCH] riscv: dts: starfive: jh7110-common: bootph-pre-ram hinting
 needed by boot loader

Add bootph-pre-ram hinting to jh7110-common.dtsi:
  - i2c5_pins and i2c-pins subnode for connection to eeprom
  - eeprom node
  - qspi flash configuration subnode
  - memory node
  - mmc0 for eMMC
  - mmc1 for SD Card
  - uart0 for serial console

  With this the U-Boot SPL secondary program loader may drop such overrides.
