The call to of_platform_populate(NULL, of_default_bus_match_table, NULL,
NULL) is now implied by having no init_machine callback in the machine
descriptor, so we can save a couple of lines in those machines that
do not need to do anything else.

This part was wrong, sorry. In the kernel I used as a base, we
actually still need exynos4_auxdata_lookup, so this patch actually
changes the behavior. In the for-next branch however, the auxdata
is gone.

Those two files don't exist any more; they were merged with
board-dt-tegra20.c and all squashed into the new tegra.c.

Right, I also noticed this when merging with the latest for-next
branch. The merged code refers to auxdata, so I'll drop the above
two without a replacement.
