If the boot firmware does not support ACPI we need a way to pass device configuration information to the drivers. The unified device properties API already supports passing platform data via properties so let's take advantage of that and allow probe drivers to pass set of properties to the host controller driver. In order to do that we need to be able to modify the MFD cell corresponding the host controller, so make the core driver to take copy of the cell instead of using it directly. Then we can assign info->pset to the resulting copy of a cell and let the MFD core to assign that to the resulting device.
