soundwire: qcom: adjust autoenumeration timeout 

[ Upstream commit 74da272400 ]

Currently timeout for autoenumeration during probe and bus reset is set to
2 secs which is really a big value. This can have an adverse effect on
boot time if the slave device is not ready/reset.
This was the case with wcd938x which was not reset yet but we spent 2
secs waiting in the soundwire controller probe. Reduce this time to
1/10 of Hz which should be good enough time to finish autoenumeration
if any slaves are available on the bus.
