trx: Add "maxdlynb" VTY command to control max TA for Normal Bursts.
Originally `maxdly` command in osmo-trx was contrlling max TA for Normal Bursts.
This was not a proper behaviour, because it was used to "control maximum
distance a handset can attach from" which is controlled by Access Bursts max TA.
Osmo-trx was corrected to apply `maxdly` to Access Bursts and a new command was
introduced to contrl max TA for Normal Bursts - `maxdlynb`. This patch adds
support for this configuration command into osmo-bts-trx.
If you wonder why would you need that - some test equipment (namely R&S CMD57)
has really bad timing sync and can generate signal a few symbols off. That
prevents osmo-trx from properly receiving otherwise perfectly good bursts
generated by CMD57. This configuration is a solution for this.
