AFAICT, the new feature will be mostly useful on HW with FPGA. I expect 
that some users may not want this feature (for instance because the HW 
doesn't have FPGA), so I think it would be best to introduce a new 
Kconfig to enable the new feature.
This could then be used to decide whether libfdt should be part of .init 
or not.
Cheers,
