Ok, I agree that optimising the platform data here is desirable, but I
think we will have to stick with this atm as the twl driver has some
rather annoying limitations that make optimising things like this a pita
atm.

I guess we should look at fixing the twl driver within TI in order to
make it more adaptable (i.e. support future twl ICs) and also a non
singleton device.
