drm/amdgpu: fix GRBM read timeout when do mes_self_test 

commit 36e7ff5c13 upstream.

Use a proper MEID to make sure the CP_HQD_* and CP_GFX_HQD_* registers
can be touched when initialize the compute and gfx mqd in mes_self_test.
Otherwise, we expect no response from CP and an GRBM eventual timeout.
