drm/amdgpu/gfx12.1: Don't fetch default register values from hardware in mqd init
1. We can't assure the fetched values are always default register values.
Observing non-zero cp_hqd_pq_rptr in mes_v12_1_self_test->init_mqd()
where no GRBM_GFX_CNTL is specified.
2. See commit fc3c139cf043 ("drm/amdgpu/gfx12: don't read registers in mqd init").
