ASoC: swr-wcd: Reduce latency for cold start on speaker

In SDM660 WSA speaker using MSM over soundwire version,
observe high cold start latency. As interrupt is disabled,
broadcast ack is not received which results in 200ms higher
latency. Reduce latency impact by blocking only for 10ms
for MSM over soundwire version.
