drm/panfrost: Add madvise and shrinker support

Add support for madvise and a shrinker similar to other drivers. This
allows userspace to mark BOs which can be freed when there is memory
pressure.

Unlike other implementations, we don't depend on struct_mutex. The
driver maintains a list of BOs which can be freed when the shrinker
is called. Access to the list is serialized with the shrinker_lock.

Merge tag 'drm-next-2019-05-09' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.

There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.

i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.

There are also some rcar-du patches which crossover with media tree
but all should be acked by Mauro.

Summary:

- expose FB_DAMAGE_CLIPS to atomic userspace

- 64-bit dma-fence seqno comparison fixes
- move initial fb config code to core
- gem fence array helpers for Lima
- ability to remove legacy support code if no drivers requires it (removes 10% of drm.ko size)
- lease fixes

ttm:
- unified DRM_FILE_PAGE_OFFSET handling
- Account for kernel allocations in kernel zone only

panel:
- OSD070T1718-19TS panel support
