    bdw: Update obvious missing blit support

    This provides a macro that allows us to update all the arbitrary blit
    commands we have stuck throughout the code. It assumes we don't actually
    use 64b relocs (which is currently true). This also allows us to easily
find
    all the areas we need to update later when we really use the upper dword.

    This block was done mostly with a sed job, and represents the easier
    in test blit implementations.
