dev-amdgpu: Default MMIO reads when previously written

If an MMIO was previously written and the driver reads it, we should
return the value that was previously read. This overwrites the MMIO
trace value which is the last resort fallback for finding an MMIO value.
This is needed to initialize newer GPU devices in gem5.
