Randy found that with the following Kconfig settings we have duplicate
definitions (e.g. __inittest()) in sdhci-of-aspeed due to competing
module_init()/module_exit() calls from kunit and driver the itself.
```
CONFIG_MMC_SDHCI_OF_ASPEED=m
CONFIG_MMC_SDHCI_OF_ASPEED_TEST=y
```
Conditionally open-code the kunit initialisation to avoid the error.
