drm/i915: Introduce pin_params.needs_physical

Browse source

Add a new flag pin_params.needs_physical to inform the pinning
code that the display needs a physical address and not GGTT
address.

This isn't strictly necessary as the current phys_alignment!=0
check is enough in practice. But theoretically one could have
needs_physical==true without any alignment requirements. And
having an explicit flag feels a bit less magical.
