Revert wait for enumeration from soundwire probe as it seems
unnecessary and device enumeration is anyway not happening here,
hence this api is blocking till it completes max wait time.
Also, as device enumeration event is dependent on wcd938x probe to be
completed, its of no use waiting here.
Waiting here increasing the boot time almost 4 seconds and impacting
other modules like touch screen.
