Hi Stefan,

The const declaration for char* is actually duplicated, however
the array of strings is currently not constant. However, typically
the dt_compat array is declared as const char *const. Follow
that convention and also add the __initconst macro for constant
initialization data.

Thanks for submitting. We will test this.
