    Fix build errors that happen when CONFIG_LOGFS=y and CONFIG_MTD=m:
    
      fs/built-in.o: In function `logfs_mount':
      super.c:(.text+0x92a6f): undefined reference to `logfs_get_sb_mtd'
      fs/built-in.o: In function `logfs_get_sb_bdev':
      (.text+0x93530): undefined reference to `logfs_get_sb_mtd'
    
    This patch avoids the error by changing the dependencies of logfs in a
    way that we can no longer configure logfs as built-in when the MTD core
    is a loadable module, while leaving the dependency to require at least
    one of MTD or BLOCK to be enabled.
