drm/i915: Introduce the plane->min_alignment() vfunc
...
Different hardware generations have different scanout alignment
requirements. Introduce a new vfunc that will allow us to
make that distinction without horrible if-ladders.
For now we directly plug in the existing intel_surf_alignment()
and intel_cursor_alignment() functions.
For fbdev we (temporarily) introduce intel_fbdev_min_alignment()
that simply queries the alignment from the primary plane of
the first crtc.
TODO: someone will need to fix xe's alignment handling

...
Rename the fb pinning functions such that their name directly
informs us what gets pinned into which address space.

drm/i915: Constify 'fb' in during pinning
...
Make the 'fb' pointers const in the pinning code. We never
want to mutate these. Also nuke a few aliasing fb vs. intel_fb
cases by just using the more specific type everywhere in the
same function.

drm/i915: Rename ggtt_view as gtt_view
...
So far, different views (normal, partial, rotated and remapped)
into the same object are only supported for GGTT mappings.
But with the upcoming VM_BIND feature, PPGTT will also use the
partial view mapping. Hence rename ggtt_view to more generic
gtt_view.

This just moves this code out of the i915_display.c into a new
