Bard Liao 9026118f20 soundwire: Add generic bandwidth allocation algorithm
This algorithm computes bus parameters like clock frequency, frame
shape and port transport parameters based on active stream(s) running
on the bus.

Developers can also implement their own .compute_params() callback for
specific resource management algorithm, and set if before calling
sdw_add_bus_master()

Credits: this patch is based on an earlier internal contribution by
Vinod Koul, Sanyog Kale, Shreyas Nc and Hardik Shah. All hard-coded
values were removed from the initial contribution to use BIOS
information instead.

SoundWire is a 2-Pin interface with data and clock line ratified
by the MIPI Alliance. SoundWire is used for transporting data
typically related to audio functions. SoundWire interface is
optimized to integrate audio devices in mobile or mobile inspired
systems. Say Y to enable this subsystem, N if you do not have such
a device

If you have an Intel platform which has a SoundWire Master then
enable this config option to get the SoundWire support for that
device.
