mfd: Add support for Intel Sunrisepoint LPSS devices The new coming Intel platforms such as Skylake will contain Sunrisepoint PCH. The main difference to the previous platforms is that the LPSS devices are compound devices where usually main (SPI, HSUART, or I2C) and DMA IPs are present. This patch brings the driver for such devices found on Sunrisepoint PCH.

device property: don't bother the drivers with struct property_set Since device_add_property_set() now always takes a copy of the property_set, and also since the fwnode type is always hard coded to be FWNODE_PDATA, there is no need for the drivers to deliver the entire struct property_set. The function can just create the instance of it on its own and bind the properties from the drivers to it on the spot. This renames device_add_property_set() to device_add_properties(). The function now takes struct property_entry as its parameter instead of struct property_set.
