From: Alex Deucher <alexander.deucher@amd.com>

commit 3c64bd26f7e9bd589ebe0d1ebec69ef2f784c12d upstream.

Return 2 so we can be sure the kernel has the necessary
changes for acceleration to work.

Note: This patch depends on these two commits:
 - drm/radeon: fix cut and paste issue for hawaii.
 - drm/radeon: use packet2 for nop on hawaii with old firmware
