drm/panthor: Provide a custom dma_buf implementation
Before we introduce cached CPU mappings, we want a dma_buf
implementation satisfying synchronization requests around CPU
accesses coming from a dma_buf exported by our driver. Let's
provide our own implementation relying on the default
gem_shmem_prime helpers designed for that purpose.
v5:
- New patch
v6:
- Collect R-b
v7:
- Hand-roll the dma_buf sync/import logic (was previously done by
generic prime/shmem helpers)
v8:
- No changes
