drm/amdgpu/gfx7: Make amdgpu_gfx_mqd_sw_init() usable on GFX7

Browse Source 
GFX7 supports KIQ, but amdgpu doesn't use it.
Change amdgpu_gfx_mqd_sw_init() to only allocate the MQD BO
for the KIQ on GFX8 and newer (that is, TOPAZ and newer).

This makes amdgpu_gfx_mqd_sw_init() usable on GFX7 without
any further changes to its functionality.
