Hi,

Some .dtsi files are included from inside a node and carry the
indentation of that context. This is e.g. used for the multi-die
Apple SoCs and dt-check-style currently interprets that as part
of the indent unit and reports spurious warnings for otherwise
correctly indented Apple and Broadcom fragments.

Teach indent-unit-dts to detect and validate the inherited prefix and
make indent-consistent account for it as well. Also add fixtures to
test this.

With this all arm64 device trees pass the relaxed checks.

Best,

Sven
