[PATCH 4/5] mmc: use EXPORT_SYMBOL_GPL for mmc_detect_change

[Christoph Hellwig]

mmc_detect_change is used via symbol_get, which was only ever intended
for very internal symbols like this one.  Use EXPORT_SYMBOL_GPL
for it so that symbol_get can enforce only being used on
EXPORT_SYMBOL_GPL symbols.
