Enabling a (modular) test should not silently enable additional kernel
functionality, as that may increase the attack vector for a product.

Fix this by skipping the new test when OF support is disabled instead of
selecting OF support.

Note that when OF support is disabled, the compiler optimizes away the
then unused reference to of_fwnode_ops in of_node_init(), so linking
succeeds.

Applied, thanks!

  Branch: driver-core-linus
  Tree:   git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core.git

[1/1] drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF
      commit: bb3a94a68283

The patch will appear in the next linux-next integration (typically within 24
hours on weekdays).

The patch is queued up for Linus's tree and should land in the next -rc release.
