[PATCH v2 1/4] mmc: sdhci-of-aspeed: Fix link failure for SPARC

Resolves the following build error reported by the 0-day bot:

    ERROR: "of_platform_device_create" [drivers/mmc/host/sdhci-of-aspeed.ko] undefined!

SPARC does not set CONFIG_OF_ADDRESS so the symbol is missing. Guard the
callsite to maintain build coverage for the rest of the driver.
