drm/i915: Prevent MI_DISPLAY_FLIP straddling two cachelines on IVB
commit f66fab8e1cd6b3127ba4c5c0d11539fbe1de1e36 upstream.
According to BSpec the entire MI_DISPLAY_FLIP packet must be contained
in a single cacheline. Make sure that happens.
v2: Use intel_ring_begin_cacheline_safe()
v3: Use intel_ring_cacheline_align() (Chris)
