soundwire: add debugfs support
Add base debugfs mechanism for SoundWire bus by creating soundwire root and master-N and slave-x hierarchy. Also add SDW Slave SCP, DP0 and DP-N register debug file. Registers not implemented will print as "XX" Credits: this patch is based on an earlier internal contribution by Vinod Koul, Sanyog Kale, Shreyas Nc and Hardik Shah.
