Ed Blake 9b4acd33dd ASoC: img-i2s-out: Add suspend / resume handling
Implement suspend and resume callbacks to save and restore register
state, to support platforms where the power is disabled during suspend.

In future the driver could be converted to use regmap which would
simplify the suspend and resume code.

Ed Blake 6f9dfab7fc ASoC: img-i2s-out: Rename suspend / resume funcs
Rename suspend and resume functions to runtime_suspend and
runtime_resume, which is what they actually are. This will avoid
confusion when adding suspend and resume functions in a subsequent
patch.

Philipp Zabel 3a4e1b9311 ASoC: img: explicitly request exclusive reset control
Commit a53e35db70 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.

No functional changes.
