As the ownership is now Hitachi Power Grids, change the license string and adapt the compatible string in DTS files. For kmeter1.dts we change it to "keymile,KMETER1" for now, as this is then compliant with what is submitted to the linux kernel. All other boards don't have a upstreamed version in linux mainline.
