We update 'extra-y' based on CONFIG_OF_ALL_DTBS three times. It would be
far more straight forward if we rather update dtb-y to include all .dtb
files if CONFIG_OF_ALL_DTBS is enabled.

Add a generic rule to apply fdtoverlay in Makefile.lib, so every
platform doesn't need to carry the complex rule. This also automatically
adds "DTC_FLAGS_foo_base += -@" for all base files.
The platform's Makefile only needs to have this now:
foo-dtbs := foo_base.dtb foo_overlay1.dtbo foo_overlay2.dtbo
dtb-y := foo.dtb
We don't want to run schema checks on foo.dtb (as foo.dts doesn't exist)
and the Makefile is updated accordingly.

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.

In order to build-test the same unit-test files using fdtoverlay tool,
move the device nodes from the existing overlay_base.dts and
testcases_common.dts files to .dtsi counterparts. The .dts files now
include the new .dtsi files, resulting in exactly the same behavior as
earlier.
The .dtsi files can now be reused for compile time tests using
fdtoverlay (will be done by a later commit).
This is required because the base files passed to fdtoverlay tool
shouldn't be overlays themselves (i.e. shouldn't have the /plugin/;
tag).
Note that this commit also moves "testcase-device2" node to
testcases.dts from tests-interrupts.dtsi, as this node has a deliberate
error in it and is only relevant for runtime testing done with
unittest.c.

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.
