We need a single mutex for all 4 shared SMBus ports on the SB800. A per-port mutex doesn't protect us from concurrent access. In theory the mutex should be per PCI device, however in practice we know that there's only ever a single instance of the device in a given system so we can use a global. Also take the mutex during initialization, as first port may be already in use when second port is initialized.
