You should never be passing regulator names through platform data, this
appears to be broken.  You should be using the struct device to
distingish between multiple instances and using whatever the actual
supply names are for multiple supplies on the same device.

Looking at this without seeing the datasheet I'd expect these would end
up as vmmcn for suitable values of n.

This is a separate change and is OK - it's this way as historically the
regulator API returned a non-NULL pointer when built out.

This will break users of this driver on any other platform - the naming
of the driver suggests that it's not specific to your SoC.
