[Buildroot] [PATCH 6/7] package/rpi-firmware: install DTB blobs

If we compile a DT-aware kernel, or the user wants them, install the DTB
blobs:
- standard DTBs for standalon A/B and A+/B+ models;
- overlay DTBs for the 'hats' addon boards.
The only configurations allowed are:
- no kernel enabled : prompt the user
- kernel enabled without DT support : hide the prompt
- kernel enabled with DT support : show the prompt, force the option
Install the DTBs as per the traditional layout expected by all RPi
users, that is:
- base DTBs alongside the other boot files;
- overlay DTBs in a sub-directory.
