drm/tegra: Changes for v4.17-rc1

Browse source 
This fixes mmap() for fbdev devices by providing a custom implementation
 based on the KMS variant. This is a fairly exotic case these days, hence
 why it is not flagged for stable.
 
 There is also support for dedicating one of the overlay planes to serve
 as a hardware cursor on older Tegra that did support hardware cursors
 but not RGBA formats for it.
 
 Planes will now also export the IN_FORMATS property by supporting the
 various block-linear tiling modifiers for RGBA pixel formats.
 
 Other than that, there's a bit of cleanup of DMA API abuse, use of the
 private object infrastructure for global state (rather than subclassing
 atomic state objects) and an implementation of ->{begin,end}_cpu_access
 callbacks for PRIME exported buffers, which allow users to perform cache
 maintenance on these buffers.
