fix(omnirig): a Yaesu in split tunes both VFOs to the spot

The generic Freq write lands on the TX VFO when split is engaged: an FT-2000
moved B and left A — the receiver — behind, so a spot click QSYed the
transmitter and nothing audible changed; without split the same write moved A.
With split on (and the operator on MAIN), FreqA and FreqB are both written,
so the radio arrives on the spot whole, split left as the operator had it.
