The same PMIC may be attached multiple ways, and multiple different PMIC
types may be attached.

So for example on the Baytrail/T platforms (ASUS T100 etc) you have
crystal cove via i2c, but a vendor could use a different PMIC - and there
will of course always be new PMIC devices coming along.

Equally on a Z2760 or similar (eg the Lenovo tablet 2) you may well have
the same PMIC attached to the system control unit. While there's nobody
afaik trying to sync the Android trees for Clovertrail+ with upstream at
this point I know there are external to Intel folks working on it for fun
and we need to allow for that.
