Allow FDT_DTS_FILE to be a list, either in the makedtb target, or in a

kernel config file. If you also want to have a static DTB compiled
into your kernel, however, it cannot be a list. We have no mechanism
in the kernel for picking one, so that doesn't make sense and will
result in a compile-time error.
