Isn't this what CONFIG_MMC_BLOCK_MINORS is for? It does limit you to 256 minors total, and therefore the number of supported MMC's is equal to 256/CONFIG_MMC_BLOCK_MINORS, but I've never heard of an Android device with support for more than 4 MMC/SD cards (including eMMC's), and I would seriously question anyone who has the need for more than 32 partitions on the root device for a phone/tablet/television.
