From: Frank Rowand <frank.rowand@xxxxxxxx>

In drivers/of/unittest-data/:
- Rename .dts overlay source files to use .dtso suffix.
- Add Makefile rule to build .dtbo.o assembly file from overlay
.dtso source file.
- Update Makefile to build .dtbo.o objects instead of .dtb.o from
unittest overlay source files.

Modify driver/of/unitest.c to use .dtbo.o based symbols instead of
.dtb.o

Modify scripts/Makefile.lib %.dtbo rule to depend upon %.dtso instead
of %.dts

Rename .dts overlay source files to use .dtso suffix in:
arch/arm64/boot/dts/freescale/
arch/arm64/boot/dts/xilinx/
