This expose modifier support on GFX9+.

Only modifiers that can be rendered on the current GPU are
added. This is to reduce the number of modifiers exposed.

The HW could expose more, but the best mechanism to decide
what to expose without an explosion in modifiers is still
to be decided, and in the meantime this should not regress
things from pre-modifiers and does not risk regressions as
we make up our mind in the future.

v2:
  - Added comment that D on Raven is only valid for 64bpp
    and will be filtered based on format later.
  - Removed D tiling modes that weren't useful for 64bpp
    on GFX10+.

v4: Add AMDGPU_FAMILY_VGH case.

For DCC we will use 2/3 planes to avoid X rendering to the frontbuffer
with DCC compressed images. To make this work with the core KMS
validation we need to add extra formats with the extra planes.

However, due to flexibility we set bpp = 0 for the extra planes and
do the validation ourselves.

This adds modifiers for GFX9+ AMD GPUs.

As the modifiers need a lot of parameters I split things out in
getters and setters.
  - Advantage: simplifies the code a lot
  - Disadvantage: Makes it harder to check that you're setting all
                  the required fields.

The tiling modes seem to change every generation, but the structure
of what each tiling mode is good for stays really similar. As such
the core of the modifier is
 - the tiling mode
 - a version. Not explicitly a GPU generation, but splitting out
   a new set of tiling equations.

Sometimes one or two tiling modes stay the same and for those we
specify a canonical version.

Then we have a bunch of parameters on how the compression works.
Different HW units have different requirements for these and we
actually have some conflicts here.

e.g. the render backends need a specific alignment but the display
unit only works with unaligned compression surfaces. To work around
that we have a DCC_RETILE option where both an aligned and unaligned
compression surface are allocated and a writer has to sync the
aligned surface to the unaligned surface on handoff.

Finally there are some GPU parameters that participate in the tiling
equations. These are constant for each GPU on the rendering/texturing
side. The display unit is very flexible however and supports all
of them :|

Some estimates:
 - Single GPU, render+texture: ~10 modifiers
 - All possible configs in a gen, display: ~1000 modifiers
 - Configs of actually existing GPUs in a gen: ~100 modifiers

For formats with a single plane everything gets put in a separate
DRM plane. However, this doesn't fit for some YUV formats, so if
the format has >1 plane, we let the driver pack the surfaces into
1 DRM plane per format plane.

This way we avoid X11 rendering onto the frontbuffer with DCC, but
still fit into 4 DRM planes.
