IB/ipath: iba6110 rev4 GPIO counters support
On iba6110 rev4, support for three more IB counters were added. The
LocalLinkIntegrityError counter, the ExcessiveBufferOverrunErrors
counter and support for error counting of flow control packets on an
invalid VL. These counters trigger GPIO interrupts and the sw keeps
track of the counts. Since we also use GPIO interrupts to signal packet
reception, we need to turn off the fast interrupts, or we risk losing a
GPIO interrupt.
