The workaround database tells us to set this bit, even though the bspec indicates the bit doesn't exist on these platforms. Since this is a write-only register, we also can't read back its value to verify whether it's actually working or not. For now we'll trust that the workaround database knows what it's talking about; if not, the hardware will just ignore the attempt to write to a non-existent bit and it shouldn't cause any problems.
