In this case the board can effectively eliminate 800MHz operation
through the regulation constraints as it requires 1.3V rather than 1.2V.
IIRC the device always comes up at full speed so the boot state also
constrains things with the current system - there's no code to reclock
the PLLs so if we boot up at 667MHz then 800MHz is inaccessible.
