log message:
Attempt to follow the correct procedure for synchronising with the
system BIOS to disable legacy device emulation as per the "EHCI
Extended Capability: Pre-OS to OS Handoff Synchronisation" section
of the EHCI spec. BIOSes that implement legacy emulation using SMIs
are supposed to disable the emulation when this procedure is performed.
tested on various archs by jsg@ and me
ok pascoe@, looks sane jsg@
