flash-kernel: Add vendor path for some arm64 machines

I'm submitting this to the Debian bug tracking system, since this isn't
directly related to u-boot. I've dropped most of the CCs on the thread,
presumably should also drop the u-boot CC on follow-ups.

It probably would fall back to the /boot/dtb-$version symlinks...

Yes, I believe this was intentional to smooth the transition without
breaking booting for some machines...
