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
