Minor, optional suggestion below.

This goto was added in 4af307f57426 ("mmc: sdhci-of-aspeed: Fix
kunit-related build error") to allow for this extra call to
aspeed_sdc_tests_init().

This could now be reverted back to what is
        rc = platform_driver_register(&aspeed_sdc_driver);
        if (rc < 0)
               platform_driver_unregister(&aspeed_sdhci_driver);

        return rc;

but let's see what the maintainers think.
