Chris commit "drm/i915: Introduce guard pages to i915_vma" was
"cunningly" changing display_alignment to u32 from u64. The
reason is that the display GGTT is and will be limited o 4GB.
Put it in a separate patch and use "max(...)" instead of
"max_t(64, ...)" when asigning the value. We can safely use max
as we know beforehand that the comparison is between two u32
variables.
