omap-serial: make serial_omap_restore_context depend on CONFIG_PM_RUNTIME

The function serial_omap_restore_context is called only from
serial_omap_runtime_resume which depends on CONFIG_PM_RUNTIME. Make
serial_omap_restore_context also compile conditionally.

if CONFIG_PM_RUNTIME is not defined below warn may be seen.
