[PATCH] mtd: cs42l43: use modern PM macro helpers

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The old SET_SYSTEM_SLEEP_PM_OPS/SET_RUNTIME_PM_OPS macros required enclosing
the function definitions in an #ifdef or marking them __maybe_unused:

drivers/mfd/cs42l43.c:1138:12: error: 'cs42l43_runtime_resume' defined but not used [-Werror=unused-function]
 1138 | static int cs42l43_runtime_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~~~~~
drivers/mfd/cs42l43.c:1124:12: error: 'cs42l43_runtime_suspend' defined but not used [-Werror=unused-function]
 1124 | static int cs42l43_runtime_suspend(struct device *dev)

 1076 | static int cs42l43_suspend(struct device *dev)
      |            ^~~~~~~~~~~~~~~

Use the modern replacements to avoid the warnings without those annotations.

Commit title has typo. mtd should be mfd.

Charles already sent a patch for this. We're waiting for Lee to merge it.
