of/unittest: Fix of_platform_depopulate test case
The previous commit, "of/unittest: early return from test skips tests"
exposed broken tests for the of_platform_unpopulate() function. The
problem was the populate and depopulate calls were not symmetrical like
they were intended to be, and unpopulate depends on the parent device to
have it's of_node pointer pointing to the parent device node. Fix these
bugs so that the test case works correctly.
In the process, the test_bus used as a container for the test devices
has been changed from a statically allocated struct device (which is
bad) to a properly allocated device with a .release() method (which is
good). This stops the test code from being a bad example of abusing the
device model.
