[M] Change in osmo-bsc[master]: nokia_site: add function to unlock and reset TRXes

( https://gerrit.osmocom.org/c/osmo-bsc/+/39652?usp=email ) Change subject: nokia_site: add function to unlock and reset TRXes ...................................................................... nokia_site: add function to unlock and reset TRXes We have a long outstanding issue with TRX RSL bootstrap, espcially with BTSes with more than one TRX. The more TRX a BTS has, the more time it takes for it get to a ready state. This commit changes the TRX bootstrap logic as the following: 1. During OML initial config, all TRXes are configured locked. This gives a better controled state of TRXes, and the BTS enough time to do internal checks, SW load etc. 2. BTS_CONF_COMPL usde as entry point for the RSL bootstrap. 3. Unlock all TRXes, and give the BCCH TRX a reset. 4. Start RSL bootstrap. Runtime tested with InSite and a MetroSite with 4 TRXes.
