pieeprom-2020-06-03: Bootmode tweaks and fix issue with > 4TB drives - BETA

Browse Source 
* Resolve: Unable to boot from USB MSD - Seagate 5Tb HDD backup drive #139
* Increase USB MSD timeout from 10 to 20 seconds.
* Max retries now default to zero because the default BOOT_ORDER includes
  restart (0xf). Therefore, each boot-mode is now tried once before moving
  to the next mode. The retries mechanism is largely redudant now that
  the loop/restart mode exists.
* If TFTP fails and network boot retries > 0 then wait 5 seconds before
  retrying to avoid overloading a misconfigured TFTP server.
* Map undefined boot-modes in BOOT_ORDER to SD (0x1) instead of stopping.
* Add missing pieeprom-2020-05-28

they are different to the current image, before doing a watchdog reset.
This should make it easier to update the bootloader for network
booted setups because an SD card is not required for recovery.bin.
