i965: Enable resource streamer for the batchbuffer
Check first if the hardware and kernel supports resource streamer. If this is allowed, tell the kernel to enable the resource streamer enable bit on MI_BATCHBUFFER_START by specifying I915_EXEC_RESOURCE_STREAMER execbuffer flags. v2: - Use new I915_PARAM_HAS_RESOURCE_STREAMER ioctl to check if kernel supports RS (Ken). - Add brw_device_info::has_resource_streamer and toggle it for Haswell, Broadwell, Cherryview, Skylake, and Broxton (Ken). v3: - Update I915_PARAM_HAS_RESOURCE_STREAMER to match updated kernel. v4: - Always inspect the getparam.value (Chris Wilson). v5: - Fold redundant devinfo->has_resource_streamer check in context create into init screen.
