ALSA: hda: cix-ipbloq: Use modern PM ops

When building without CONFIG_PM_SLEEP, there are several warnings (or
errors with CONFIG_WERROR=y / W=e) from the cix-ipbloq driver:

  sound/hda/controllers/cix-ipbloq.c:378:12: error: 'cix_ipbloq_hda_runtime_resume' defined but not used [-Werror=unused-function]
    378 | static int cix_ipbloq_hda_runtime_resume(struct device *dev)
        |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  sound/hda/controllers/cix-ipbloq.c:362:12: error: 'cix_ipbloq_hda_runtime_suspend' defined but not used [-Werror=unused-function]
    362 | static int cix_ipbloq_hda_runtime_suspend(struct device *dev)
        |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  sound/hda/controllers/cix-ipbloq.c:349:12: error: 'cix_ipbloq_hda_resume' defined but not used [-Werror=unused-function]
    349 | static int cix_ipbloq_hda_resume(struct device *dev)
        |            ^~~~~~~~~~~~~~~~~~~~~
  sound/hda/controllers/cix-ipbloq.c:336:12: error: 'cix_ipbloq_hda_suspend' defined but not used [-Werror=unused-function]
    336 | static int cix_ipbloq_hda_suspend(struct device *dev)
        |            ^~~~~~~~~~~~~~~~~~~~~~

When CONFIG_PM and CONFIG_PM_SLEEP are unset, SET_SYSTEM_SLEEP_PM_OPS()
and SET_RUNTIME_PM_OPS() evaluate to nothing, so these functions appear
unused to the compiler in this configuration.

Use the modern SYSTEM_SLEEP_PM_OPS and RUNTIME_PM_OPS macros to resolve
these warnings, which is what they are intended to do. Additionally,
wrap &cix_ipbloq_hda_pm in pm_ptr() to ensure the compiler can drop the
entire structure when CONFIG_PM is unset.
