[PATCH 02/13] ASoC: cs35l56: Make cs35l56_system_reset() code more generic

Richard Fitzgerald

From: Simon Trimmer <simont@opensource.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.
