pieeprom-2025-08-27: 2711: Fix PARTITION property to allow default (0) partition property to be overridden (latest)

* Fix PARTITION property to allow default (0) partition to be overridden
  Fix the partition selection to allow the bootloader PARTITION
  property to override the reboot partition number if the reboot
  argument is 0 or > 31. Previously, it was only allowing
  partition numbers > 31 to be overridden.
  See: #743
* Enable RPIBOOT in BOOT_ORDER / set-reboot-order
  Previously, rpiboot required the bootrom to have initialised
  rpiboot before running the firmware. Update the rpiboot
  initialisation so that rpiboot to be enabled after booting from
  SPI flash.
  This could be selectively enabled by setting BOOT_ORDER property
  (0x3) behind a GPIO conditional in the EEPROM config. On Pi5, the
  set_reboot_order config.txt option or mailbox property can be
  used to set a one-time boot-order on
  N.B. There is no timeout for RPIBOOT so this should only be set
  as the last boot mode OR used with a boot_watchdog.
