This alleviates us from updating the drivers every time a new PMIC comes out. It's still recommended that we update the binding with new PMIC models and always specify the specific model for the MPPs and gpios before the generic compatible string in devicetree, but this at least cuts down on adding more and more compatible strings to the drivers until we actually need them.

Ivanov Reviewed-by: Bjorn Andersson --- We can also figure out the number of the pins from the number of interrupts, so we really don't need to even look at the size of the reg property or model number for the spmi and ssbi modules. I'll propose that change as well tomorrow.
