mfd: timberdale: Attach device properties to TSC2007 board info

Switch over to using software nodes/properties to describe the
touchscreen instead of using the legacy platform data. This will
allow to drop support for the platform data from TSC2007 driver
and rely solely on the generic driver properties.

Note: "model" is not part of defined device properties and is not
used by the TSC2007 driver, so it can be safely dropped.
