cramfs: fix MTD dependency
With CONFIG_MTD=m and CONFIG_CRAMFS=y, we now get a link failure: fs/cramfs/inode.o: In function `cramfs_mount': inode.c:(.text+0x220): undefined reference to `mount_mtd' fs/cramfs/inode.o: In function `cramfs_mtd_fill_super': inode.c:(.text+0x6d8): undefined reference to `mtd_point' inode.c:(.text+0xae4): undefined reference to `mtd_unpoint' This adds a more specific Kconfig dependency to avoid the broken configuration. Alternatively we could make CRAMFS itself depend on "MTD || !MTD" with a similar result.
