mailbox: imx: Mark PM functions as __maybe_unused
When CONFIG_PM and CONFIG_PM_SLEEP are unset, the following warnings occur: drivers/mailbox/imx-mailbox.c:638:12: warning: 'imx_mu_runtime_resume' defined but not used [-Wunused-function] 638 | static int imx_mu_runtime_resume(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~~ drivers/mailbox/imx-mailbox.c:629:12: warning: 'imx_mu_runtime_suspend' defined but not used [-Wunused-function] 629 | static int imx_mu_runtime_suspend(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~~~ drivers/mailbox/imx-mailbox.c:611:12: warning: 'imx_mu_resume_noirq' defined but not used [-Wunused-function] 611 | static int imx_mu_resume_noirq(struct device *dev) | ^~~~~~~~~~~~~~~~~~~ drivers/mailbox/imx-mailbox.c:601:12: warning: 'imx_mu_suspend_noirq' defined but not used [-Wunused-function] 601 | static int imx_mu_suspend_noirq(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~ Mark these functions as __maybe_unused, which is the standard procedure for PM functions.
