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.
