Unify code converting between the different txpower values. Always add/remove
the combined txpower delta before dividing half-dB values.
Also fix the combined txpower delta values. The correct half-dB delta for
3 chains is 9, not 8.

Setting the tx power by manipulating EEPROM may in some cases not be enough,
since it only covers the base target power and not per-rate offsets.
In other cases, it could limit tx power of rates too much, possibly reducing
throughput or range.
Use firmware support for applying per-rate limit and power offsets for
different values of Nss.
