of: unittest: document intentional interrupt-map provider build warning
A recently implemented dtc compiler warning reports a dts problem
via a build warning:
drivers/of/unittest-data/tests-interrupts.dtsi:32.26-35.6: Warning (interrupt_map): /testcase-data/interrupts/intmap1: Missing '#address-cells' in interrupt-map provider
The warning will be addressed by a separate patch by suppressing the
warning for .dts files that include this .dtsi. This patch documents
why the warning is due to a deliberately incorrect .dtsi file so that
no one will fix the .dtsi file to prevent the build warning.
