Turn on NO_MIXED_MODE for amd64 generic. It turns out that all the
known samples of broken chipsets that needed mixed mode in the first place
are so broken (ie: locks up) that we can't use IO APIC mode at all and it
needs to be turned off in the bios. So, the MIXED_MODE penalty on the
good chipsets gained nothing.
