    mpc85xx: Fix output location of padded dtb
    
    In commit 7e614820a892 ("mpc85xx: add support for Extreme Networks
    WS-AP3825i"), we borrowed a recipe convention from apm821xx for device
    tree blob padding. Unfortunately, in the apm821xx target, the image
    recipes name the device tree blob differently, meaning that in
    mpc85xx, the padded dtb is never consumed.
    
    Change the definition of `Build/dtb` so that it outputs the padded dtb
    to the correct location for it to be consumed.
    
    Also, rename the recipe to `Build/pad-dtb`, so it is clear we
    are building and padding the device tree blob.
    
    This change fixes Github issue #9779 [1].
