L1SAP: Increase resolution of reported burst timing
Before this patch we had: * osmo-bts-trx internally using 1/256th bit/symbol period * osmo-bts-sysmo internally using 1/4 bit/smbol period * PCU interface using 1/4 * L1SAP interface using 1/4 * measurement processing code on top of L1SAP using 1/256 So for sysmo/lc15/octphy we are not loosing resolution, but for osmo-bts-trx we're arbitrarily reducing the resolution via L1SAP only then to compute with higher resolution again. Let's change L1SAP to use 1/256 bits and hence not loose any resolution. This requires a corresponding change in libosmocore for l1sap.h, which is found in Change-Id Ibb58113c2819fe2d6d23ecbcfb8b3fce4055025d Change-Id: If9b0f617845ba6c4aa47969f521734388197c9a7
