drivers/rtc/rtc-tps65910.c: fix invalid pointer access on _remove()
The tps65910_rtc data is registered as the platform driver data in
_probe(= ). Therefore the tps65910_rtc should be used on unregistering
the rtc device. And device pointer should be retrieved from the
platform_device structure.
This patch fixes the below oops:
Unable to handle kernel NULL pointer dereference at virtual address 00000008
