Subject: [PATCH v4 02/12] ASoC: cs35l56: Make cs35l56_system_reset() code more generic

From: Simon Trimmer <simont@...nsource.cirrus.com>

The function can be more easily reused in HDA if the tracking of whether
a soft reset is being performed and whether the device is connected to a
SoundWire bus is moved out of the function.
