osmo-bts-trx: refactor 'maxdly' / 'maxdlynb' commands
* Move way too verbose command description to the manuals.
* None of these commands apply immediately, correct the attributes.
** Remove meaningless call to l1if_provision_transceiver_trx().
* Make 'maxdlynb' hidden, so it only appears in the expert mode.
* One GMSK symbol actually corresponds to 550m.
