[PATCH] rtc: rtc-max6902 - set driver data in max6902_probe()

[Axel Lin <axel.lin@gmail.com>]

Current implementation does not set driver data in max6902_probe(),
thus calling platform_get_drvdata(spi) in max6902_remove() returns NULL.

Since this is a spi driver, use spi_set_drvdata/spi_get_drvdata to
set/get driver data.
