ms: Enable synchronized uplink bursts

Extend the measured SCH timing offset from the downlink to the uplink
path. In order to absorb the frame timing adjustment and remove the
potential of thread contention during the change, combine the lower
FIFO threads into single drive loop.

Force timing changes through to the UHD interface with stream flags
triggered through the updateAlignment() call.
