ARM: dts: msm: Add physical dimensions for NT35597 panel

The physical dimensions are used to determine the DPI in the
framework. If these dimensions are not provided, the framework
assumes a default DPI value which may not be suitable for the
current panel and lead to some apps drawing incorrectly.
