scsi: ufs: core: Simplify temperature exception event handling

Browse source 
This commit simplifies the temperature exception event handling by removing
the ufshcd_temp_exception_event_handler() function and directly calling
ufs_hwmon_notify_event() in ufshcd_exception_event_handler().

The ufshcd_temp_exception_event_handler() function contained a placeholder
comment for platform vendors to add additional steps if required. However,
since its introduction a few years ago, no vendor has added any additional
steps. Therefore, the placeholder function is removed to streamline the
code.
