ARM: shmobile: henninger: remove board DT

The Henninger low cost board was never sold and so had no users outside Renesas (and Cogent Embedded). Instead Renesas has made the Porter board which has mostly similar hardware. Now that the Porter board support is on par with Henninger, we can remove the Henninger's device tree file.
