Is there anything in this driver that is actually specific to any of
these two platforms/architectures? I'd don't think we should restrict
if we can avoid it (hint: the companion MSI driver is not restricted to
any architecture).

No specific dependency on these 2 architectures. Then I will remove this.

Thanks.
