rtc: rtc-stmp3xxx: remove unnecessary platform_set_drvdata()
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata = NULL when no driver is bound"). Thus, it is not needed to manually clear the device driver data to NULL.
