The list of unaffected ones are:
Pus all newer asics.
Alternatively, the list of older asics that are affected (some of
these may not even support MSI64 in the first place):
0xaab0 //verde, pitcairn, oland
It might be better to only set the msi32 flag on the above affected
asics so we don't have to worry about new ones.
