a=openpgp; fpr=ED6472765AB36EC43B3EF97AD77E3FC0562560D6 Soundwire controllers (WSA, WSA2, RX, TX) require reset lines to enable switching clock control from hardware to software. Add them along with the reset control providers. Without this reset we might hit fifo under/over run when we try to write to soundwire device registers.
