Some configurations want to enable CONFIG_KUNIT without enabling
CONFIG_OF_OVERLAY. The kunit overlay code already skips if
CONFIG_OF_OVERLAY isn't enabled, so this select here isn't really doing
anything besides making it easier to run the tests without them
skipping. Remove the select and move the config setting to the
drivers/of/.kunitconfig file so that the overlay tests can be run with
or without CONFIG_OF_OVERLAY set to test either behavior.

console.

This option should only be enabled for a development kernel. The tests

will taint the kernel with TAINT_TEST. The tests will cause ERROR and

WARNING messages to print on the console. The tests will cause stack

traces to print on the console. It is possible that the tests will

leave the devicetree in a corrupted state.

The unittest output will be verbose. Copy the output to a file

via capturing the console output or via the dmesg command. Process

this file with scripts/dtc/of_unittest_expect to reduce the

verbosity, test whether expected output is present, and to

summarize the results.
