    realtek: rtl8380-tl-sg2xxx: use a single "firmware" partition
    
    The "firmware" partition was assembled from two contiguous partitions.
    This complexity is unnecessary. Instead of using mtd-concat over
    "sys" and "usrimg1", simply declare the "firmware" partition to cover
    the flash space instead.
