drm: omapdrm: Remove legacy buffer synchronization support
The omapdrm driver uses a custom API to synchronize with the SGX GPU. This is unusable as such in the mainline kernel as the API is only partially implemented and requires additional out-of-tree patches. Furthermore, as no SGX driver is available in the mainline kernel, the API can't be considered as a stable mainline API. Now that the driver supports synchronization through fences, remove legacy buffer synchronization support. The two userspace ioctls are turned into no-ops to avoid breaking userspace and will be removed in the future.
