ASoC: SDCA: export PM helpers keyed on sdca_class_drv

The class PM callbacks pull sdca_class_drv out of drvdata, so the
built-in class_sdw_driver owns the drvdata slot. That works for the
generic case but blocks codec drivers that want to embed
sdca_class_drv in their own private struct -- they need drvdata for
their codec priv.

Split the four callbacks into exported helpers that take a
struct sdca_class_drv * directly:

  sdca_class_system_suspend()
  sdca_class_system_resume()
  sdca_class_runtime_suspend()
  sdca_class_runtime_resume()

Codec drivers can now compose these into their own dev_pm_ops without
going through drvdata.

For the built-in class_sdw_driver, add small dev_pm_ops wrappers that
fetch drv from drvdata and wire them into sdca_class_pm_ops. The ops
struct itself stays private to this file; codec drivers build their
own dev_pm_ops from the four exported helpers above.

No functional change: the built-in class_sdw_driver keeps the same PM
semantics; only the internal plumbing shifts to operate on
sdca_class_drv instead of struct device *dev.
