[UPSTREAM] Use new regulator API for pcf50633

Hi,
The changed regulator API requires that we create a platform device for
every regulator. This causes some races with devices initialization. The
attach_child_devices callback can be called only after all regulators
have been registred with the core.
I've solved this problem by using a bitmap to mark regulators as they
are registered. This way we come to know once all of them are
registered, so that we can call attach_child_devices. I've changed the
neo1973-pm-bt to use the regulator API and found it to work.
I've not touched the suspend/resume part. Suspending regulators is
done through the regulator_prepare_suspend function, which can be called
from pcf50633_suspend ? But how do we get the regulators back to active
state on resume ?

If you say yes here you get support for Philips PCF50633
