[PATCH] MIPS: Alchemy: only build mmc support helpers if au1xmmc is enabled

[Christoph Hellwig]

While commit d4a5c59a955b ("mmc: au1xmmc: force non-modular build and
remove symbol_get usage") to be built in, it can still build a kernel
without MMC support and thuse no mmc_detect_change symbol at all.

Add ifdefs to build the mmc support code in the alchemy arch code
conditional on mmc support.

Fixes: d4a5c59a955b ("mmc: au1xmmc: force non-modular build and remove symbol_get usage")
