Ok, no rush on this - we can add the patch for these later when we know
which versions specify misc5.
The legacy-hal uses this bit, but does so by directly reading that
offset in attach for some reason. It's the same address as
AR5K_EEPROM_MISC5, offset 0xc9. From the HAL:

Ok, so it only works for eeprom 5.1 and better...
