[Intel-gfx] [PATCH v2 6/8] drm/i915/display: Check mappable aperture when pinning preallocated vma

From: CQ Tang When system does not have mappable aperture, ggtt->mappable_end=0. In this case if we pass PIN_MAPPABLE when pinning vma, the pinning code will return -ENOSPC. So conditionally set PIN_MAPPABLE if HAS_GMCH(). Suggested-by: Chris P Wilson Signed-off-by: CQ Tang Cc: Radhakrishna Sr
