Commit Message

Since the overlays dtb files are now named as .dtbo, there is a lot of
interest in similarly naming the overlay source dts files as .dtso.

This patch makes the necessary changes to allow .dtso format for overlay
source files.

Note that we still support generating .dtbo files from .dts files. This
is required for the source files present in drivers/of/unittest-data/,
because they can't be renamed to .dtso as they are used for some runtime
testing as well.
