drm/radeon: tweak ACCEL_WORKING2 query for hawaii
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
