transceiver: Avoid sending clock indications when trx is not powered on
Stop calling writeClockInterface() when receiving commands in Transceiver::driveControl,
otherwise it fools osmo-bts-trx clock skew check because it is always sending a clock
indication with the same fn when it issues any commands during the time in between
CMD POWEROFF and RSP POWERON, because fn is not increased during that period.
Also use mForceClockInterface flag to delay delivery of first IND CLOCK until we start
serving frames, otherwise the first one is sent and only after a long period of time
the next clock indications are sent, when the radio starts to process bursts. That makes
osmo-bts-trx unhappy because it expects to receive an IND CLOCK aprox at least every
400 frames. This way also we send the first IND CLOCK after the RSP POWERON 0 response.
