voicebus: Add function to lock the latency.
Now that increases in the latency produce less undefined behavior on the SPI
busses, provide an interface for client drivers to inform the voicebus library
to not increase the latency if underruns are detected. This can speed up loads
of the driver since latency bumps do not trigger a restart of the driver
initialization. DAHDI-278.
