Subject: [PATCH 1/2] ASoC: codecs: soundwire: increase resume timeout

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

The resume operation relies on multiple transactions to synchronize
the regmap state, make sure the timeout is one order of magnitude
larger than an individual transaction, so that timeouts of failed
transactions are detected first.
