136569e6bc kunit: provide kunit_platform_device_unregister() 
Tests may want to unregister a platform device as part of the test case
logic. Using the regular platform_device_register() with kunit
assertions may result in a platform device leak or otherwise requires
cumbersome error handling. Provide a function that unregisters a
kunit-managed platform device and drops the release action from the
test's list.

5ac7973032 platform: Add test managed platform_device/driver APIs 
Introduce KUnit resource wrappers around platform_driver_register(),
platform_device_alloc(), and platform_device_add() so that test authors
can register platform drivers/devices from their tests and have the
drivers/devices automatically be unregistered when the test is done.

This makes test setup code simpler when a platform driver or platform
device is needed. Add a few test cases at the same time to make sure the
APIs work as intended.
