Enable building all dtb files when CONFIG_OF_ALL_DTBS is enabled. The dtbs
are not really dependent on a platform being enabled or any other kernel
config, so for testing coverage it is convenient to build all of the dtbs.
This builds all dts files in the tree, not just targets listed. This
is simpler for arm64 which has a bunch of sub-dirs.

This doesn't look simpler than the arm(32) version?

I discussed this with Olof in the last version. In the ARM version, I
could have done just one line "dtb-$(CONFIG_OF_ALL_DTBS) += $(dtb-)"
to add all the disabled dtbs. On arm64, I would have to do that for
each sub-dir Makefile as well as make sure any new sub-dirs have this
line. In the end, I also prefer to build everything in the tree and
not rely on the dtbs to be explicitly listed.
