[PATCH] ARM: cygnus: fix const declaration bcm_cygnus_dt_compat

[Stefan Agner]

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.
