firewire: ohci: disable MSI on Ricoh controllers
The PCIe device FireWire (IEEE 1394) [0c00]: Ricoh Co Ltd FireWire Host Controller [1180:e832] (prog-if 10 [OHCI]) is unable to access attached FireWire devices when MSI is enabled but works if MSI is disabled. http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28251.html Hence add the "disable MSI" quirks flag for this device, or in fact for safety and simplicity for all current (R5U230, R5U231, R5U240) and future Ricoh PCIe 1394 controllers.
