of: unittest: Statically apply overlays using fdtoverlay 



Now that fdtoverlay is part of the kernel build, start using it to test
the unitest overlays we have by applying them statically. Create two new
base files static_base_1.dts and static_base_2.dts which includes other
.dtsi files.

Some unittest overlays deliberately contain errors that unittest checks
for. These overlays will cause fdtoverlay to fail, and are thus not
included for static builds.

# Apply overlays statically with fdtoverlay.  This is a build time test that

# the overlays can be applied successfully by fdtoverlay.  This does not

# guarantee that the overlays can be applied successfully at run time by

# unittest, but it provides a bit of build time test coverage for those

# who do not execute unittest.

#

# The overlays are applied on top of static_base_1.dtb and static_base_2.dtb to

# create static_test_1.dtb and static_test_2.dtb.  If fdtoverlay detects an

# error than the kernel build will fail.  static_test_1.dtb and

# static_test_2.dtb are not consumed by unittest.

# Some unittest overlays deliberately contain errors that unittest checks for.

# These overlays will cause fdtoverlay to fail, and are thus not included

#			  overlay_bad_add_dup_prop.dtbo \
