Deprecate non-DT platforms
make all platforms build the non-DT support only based on CONFIG_ATAGS
As debated in the Linaro Connect session on single zImage, we would like to make all multiplatform enabled targets DT-only in the long run. The process to get there is first making it easy to disable all non-DT code by making it conditional on CONFIG_ATAGS or a platform specific symbol depending on that. We can then
gradually make it harder to enable that code, and eventually drop all code
depending on it, one platform at a time. For the last step, we have not decided on a schedule yet, but we should now make all code conditional that is not needed
on DT platforms.
