There is only one instance of ab8500_regulator_platform_data, and it's
safe to assume we won't ever merge another one, so it's rather pointless
to pass it through multiple levels of platform data pointers.

This moves the structure and everything referenced by it into the
driver that uses it.

Well in order to do that we need to provide this call-back, where we check that the value is sane and return without error. Not that the selector isn't populated, but in our case list_voltage doesn't actually use it, so we're good.
