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.
