pieeprom-2025-01-14: 2712: Add set_reboot_order API (latest)

Browse Source 
* Add set_reboot_order API and config.txt properties
  If set_reboot_order is defined in config.txt or set via vcmailbox
  then this will override the bootloader config BOOT_ORDER property
  on the next reboot. The parameter is stored in a reset safe register
  and is cleared by the bootloader after reading it.
  Typically, the config.txt value only be used via rpiboot to
  override the boot-order on the next reboot. Otherwise, it should
  reside in a conditional section so that the boot order is not
  overridden on every reboot.
  Example, test network boot
  sudo vcmailbox 0x0003808b 4 4 0xf4612; sudo reboot
