Shaun Ruffell 4de462c3e0 wctdm24xxp, wcte12xp: Disable PCI read-line multiple command. 
There are some platforms where the read-line multiple transaction causes
packets to be dropped in the voicebus pipeline.  The only observable
behavior is that packets just go "missing" in the pipeline.  This also
only appears to affect PCI cards.

A typical 'symptom' of this problem is you may see IRQ misses increasing
without any corresponding "bumps" in latency in the kernel message log.
Normally, IRQ misses are correlated to latency bumps since that is an
indication that the host was not able to service the card interrupt in a
timely fashion. DAHDI-510 DAHDI-774
