Not necessarily because the driver won't allow tx power adjustments at all
if EEPROM_EIRP_MAX_TX_POWER is unused.

For these devices we cannot rely on the tx power output at all and maybe
it makes sense to register a max power of 0 just to tell mac80211/cfg80211
that no tx power adjustments are possible on these devices?
