regulator: fix crash caused by null driver data ...
commit fb6de923ca3358a91525552b4907d4cb38730bdd upstream.
dev_set_drvdata() needs to be called before device_register()
exposes device to userspace. Otherwise kernel crashes after it
gets null pointer from dev_get_drvdata() when userspace tries
to access sysfs entries.
