This adds the support to turn on the regulators required
for SMMUs. It is turned on during the SMMU probe and remains
'on' till the device exists.

The device always exists. Until the driver is removed perhaps?

We won't be using regulators. We'll be using power domains instead so 
please rewrite this patch accordingly.
