drm/amdgpu: don't put MQDs in VRAM on ARM | ARM64

Browse source

Issues were reported with commit 1cfb4d6121
("drm/amdgpu: put MQDs in VRAM") on an ADLINK Ampere
Altra Developer Platform (AVA developer platform).

Various ARM systems seem to have problems related
to PCIe and MMIO access.  In this case, I'm not sure
if this is specific to the ADLINK platform or ARM
in general.  Seems to be some coherency issue with
VRAM.  For now, just don't put MQDs in VRAM on ARM.
