mfd: core: propagate device properties to sub devices drivers

BugLink: http://bugs.launchpad.net/bugs/1533035
In the similar way like we do for the platform data we propagate the device
properties. For example, in case of Intel LPSS drivers we may provide a
specific property to tell the actual device driver an additional information
such as platform name.
