I'm not sure how to properly solve this. I'm not a big fan of adding a
specific Kconfig option for each and every optional feature. I'd prefer
if we get the correct thing<tm> based on just the MMC_SDHCI and
LEDS_CLASS options.

-#if defined(CONFIG_LEDS_CLASS) || defined(CONFIG_LEDS_CLASS_MODULE)
+#if defined(CONFIG_LEDS_CLASS) || (defined(CONFIG_LEDS_CLASS_MODULE)
 	&& !defined(CONFIG_MMC_SDHCI_MODULE))

perhaps?
