In the description, I linked to some kunit changes that were merged in 6.12
that now require us to enable `CONFIG_OF_OVERLAY` because we have
`CONFIG_CLK_FIXED_RATE_KUNIT_TEST` (!3401), `CONFIG_CLK_KUNIT_TEST` (!1722)
and `CONFIG_OF_OVERLAY_KUNIT_TEST` (!3405) enabled in RHEL for all arches
(that the test supports).

For powerpc we will need to disable these three kunit tests to disable
'CONFIG_OF_OVERLAY'.
