    ath79: routerboard-92x: ensure explicit bios size in DTSI
    
    The missing "size" property was acceptable in the context of a single
    DTS as the underlying device is known to have a 64KB flash, and thus
    the bios partition fit exactly between the preceding and following ones.
    
    However as this block has moved in a DTSI, for the sake of clarity and
    explicitness the size property is added to ensure that if the flash
    happens to be larger than expected, the bios partition remains properly
    sized.
