drm/panfrost: Add a PANFROST_SYNC_BO ioctl
This will be used by the UMD to synchronize CPU-cached mappings when
the UMD can't do it directly (no usermode cache maintenance instruction
on Arm32).
v2:
- Add more to the commit message
- Change the flags to better match the drm_gem_shmem_sync semantics
v3:
- Add Steve's R-b
v4:
- No changes
v5:
- Drop Steve's R-b (semantics changes requiring a new review)
v6:
- Bail out early in panfrost_ioctl_sync_bo() if op_count is zero
v7:
- Hand-roll our own bo_sync() helper
v8:
- Collect R-b
