Add a -u flag for U-Boot SPL which requests that unit tests be run. To make this work, export dm_test_main() and update it to skip test features that are not used with of-platdata.
To run the tests:
$ spl/u-boot-spl -u U-Boot SPL 2020.10-rc5 (Oct 01 2020 - 07:35:39 -0600) Running 0 driver model tests Failures: 0
At present there are no SPL unit tests.
Note that there is one wrinkle with these tests. SPL has limited memory available for allocation. Also malloc_simple does not free memory (free() is a nop) and running tests repeatedly causes driver-model to reinit multiple times and allocate memory. Therefore it is not possible to run more than a few tests at a time. One solution is to increase the amount of malloc space in sandbox_spl. This is not a problem for pytest, since it runs each test individually, so for now this is left as is.
