mcbts: Allow out of order channel setup

Previous checks on multi-channel TSC and ARFCN settings would fail
if channels were initialized out of order. Namely, if channel 0
was not configured first, osmo-trx would error on the control
interface leading osmo-bts to fail.

Allow global TSC setting on all channels with added logging notice.
Notify if channel frequency is unexpected - which may happen if
channels are setup out of order - but do no report as error.
