of: unittest: kmemleak in of_unittest_platform_populate()
commit 216830d2413cc61be3f76bc02ffd905e47d2439e upstream.
kmemleak reports several memory leaks from devicetree unittest.
This is the fix for problem 2 of 5.
of_unittest_platform_populate() left an elevated reference count for
grandchild nodes (which are platform devices). Fix the platform
device reference counts so that the memory will be freed.
Fixes: fb2caa50fbac ("of/selftest: add testcase for nodes with same name and address")
