drm/i915: enforce min GTT alignment for discrete cards
For local-memory objects we need to align the GTT addresses
to 64K, both for the ppgtt and ggtt.
We need to support vm->min_alignment > 4K, depending
on the vm itself and the type of object we are inserting.
With this in mind update the GTT selftests to take this
into account.
For compact-pt we further align and pad lmem object GTT addresses
to 2MB to ensure PDEs contain consistent page sizes as
required by the HW.
v3:
* use needs_compact_pt flag to discriminate between
64K and 64K with compact-pt
* add i915_vm_obj_min_alignment
* use i915_vm_obj_min_alignment to round up vma reservation
if compact-pt instead of hard coding
v5:
* fix i915_vm_obj_min_alignment for internal objects which
have no memory region
v6:
* tiled_blits_create correctly pick largest required alignment
v8:
* i915_vm_min_alignment protect against array overflow for mock region
