drm/i915: allow stolen, pre-allocated objects to avoid GTT allocation v2

Browse source

In some cases, we may not need GTT address space allocated to a stolen
object, so allow passing -1 to the preallocated function to indicate as
much.

v2: remove BUG_ON(gtt_offset & 4095) now that -1 is allowed (Ville)
