package/rpi-firmware: install DTB blobs
Add an option to install all the DTBs:
- standard DTBs for standalon A/B and A+/B+ models;
- overlay DTBs for the 'hats' addon boards.
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.
This requires the user provide a specially configured Linux defconfig
file, as the default ones do not enable USE_OF.
[Thomas: adjust comment explaining why we use a different version when
installing the DTBs is selected.]
