Replace Panfrost's custom memory shrinker with a common drm-shmem
memory shrinker.

Add unlocked variants of drm_gem_un/pin() functions. These new helpers
will take care of GEM dma-reservation locking for DRM drivers.
VirtIO-GPU driver will use these helpers to pin shmem framebuffers,
preventing them from eviction during scanout.

Support generic drm-shmem memory shrinker and add new madvise IOCTL to
the VirtIO-GPU driver. BO cache manager of Mesa driver will mark BOs as
"don't need" using the new IOCTL to let shrinker purge the marked BOs on
OOM, the shrinker will also evict unpurgeable shmem BOs from memory if
guest
Replace all drm-shmem locks with a GEM reservation lock. This makes locks
consistent with dma-buf locking convention where importers are responsible
for holding reservation lock for all operations performed over dma-bufs,
preventing deadlock between dma-buf importers and exporters.
Suggested-by:
Introduce common drm-shmem shrinker for DRM drivers.
To start using drm-shmem shrinker drivers should do the following:
1. Implement evict() callback of shmem object where driver should check
whether object is purgeable or evictable and perform shrinking action
2. Register shrinker using
DMA-buf core has its own refcounting of vmaps, use it instead of drm-shmem
counting. This change prepares drm-shmem for addition of memory shrinker
support where drm-shmem will use a single dma-buf reservation lock for
all operations performed over dma-bufs.

Consider this scenario:
1. APP1 continuously creates lots of small GEMs
2. APP2 triggers `drop_caches`
3. Shrinker starts to evict APP1 GEMs, while APP1 produces new purgeable
GEMs
4. msm_gem_shrinker_scan() returns non-zero number of freed pages
and causes shrinker to try shrink more
5.
This series:
1. Adds common drm-shmem memory shrinker
2. Enables shrinker for VirtIO-GPU driver
3. Switches Panfrost driver to the common shrinker

I actually tried that.
You don't want "when exists", you'd want "when forall", but that seems
to be the default.
