Some pwm vibrators have a dedicated enable GPIO that needs to be set
high so that the vibrator works. Add support for that optionally.

So this is not simply a power supply in your case controlled by a GPIO?
We truly can have both GPIO and a separate regulator?

Yes it appears to be the EN pin on the ISA1000A, see
https://electronics.stackexchange.com/q/380475

On apq8026-lg-lenok there is a similar setup for the vibration motor although 
there I don't know whether it's actually a fixed-regulator or not, but since 
the two devices were built in a similar time (without checking further) I 
could assume they both contain the same IC.
