bts: f_est_dchan(): populate UL SACCH cache
This ensures that UL SACCH blocks always contain the expected content
and a proper L1 SACCH header, rather than the dummy measurement report
hard-coded in trxcon/firmware. As a result, the BTS receives
consistent and realistic UL SACCH from the very beginning.
