>All the bits in the VBT child device type have some speciifc meaning,
>so looking for an exact match isn't always the right thing. On some
>VLVs for example the device type for eDP panels is 0x1806.
>
>If we mask out the bits that could concievably change between different
>eDP panels, we are left with the set of bits that should still
>tell us if the port is eDP or not.
