James Jones fa4f4c213f drm/nouveau/kms: Support NVIDIA format modifiers
Allow setting the block layout of a nouveau FB
object using DRM format modifiers.  When
specified, the format modifier block layout and
kind overrides the GEM buffer's implicit layout
and kind.  The specified format modifier is
validated against the list of modifiers supported
by the target display hardware.

v2: Used Tesla family instead of NV50 chipset compare
v4: Do not cache kind, tile_mode in nouveau_framebuffer
v5: Resolved against nouveau_framebuffer cleanup
