regulator: Fixes for 4.19

A collection of fairly minor bug fixes here, a couple of driver specific
ones plus two core fixes.  There's one fix for the new suspend state
code which fixes some confusion with constant values that are supposed
to indicate noop operation and another fixing a race condition with the
creation of sysfs files on new regulators.

regulator: fix crash caused by null driver data

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.

[Removed backtrace for length -- broonie]
