drm/panfrost: Add flag to map GEM object Write-Back Cacheable
Will be used by the UMD to optimize CPU accesses to buffers
that are frequently read by the CPU, or on which the access
pattern makes non-cacheable mappings inefficient.
Mapping buffers CPU-cached implies taking care of the CPU
cache maintenance in the UMD, unless the GPU is IO coherent.
v2:
- Add more to the commit message
v3:
- No changes
v4:
- Fix the map_wc test in panfrost_ioctl_query_bo_info()
v5:
- Drop Steve's R-b (enough has changed to justify a new review)
v6:
- Collect R-b
v7:
- No changes
v8:
- Fix double drm_gem_object_funcs::export assignment
