[PATCH v2 26/29] test: spl: Add a test for the MMC load method

Sat Oct 14 22:48:02 CEST 2023
Add a test for the MMC load method. This shows the general shape of tests
to come: The main test function calls do_spl_test_load with an appropriate
callback to write the image to the medium.

Changes in v2:
- Correct return value documentation for do_spl_test_load
- Explicitly invalidate FAT and MMC caches before testing
