John Sloan 4305b44108 wcxb: Fix "I/O error reported by firmware" followed by underruns
The cards affected include the TE131/3, TE235/435, A4B, and A8B.

Update all PCIe cards' firmware to increase the incoming and outgoing TDM FIFOs
to 16ms. The FIFOs will only be filled to a depth equal to the driver's latency
setting (ie. 3ms default). The total system latency is not effected. The
firmware and driver now also report the maximum DMA transaction time when in
DEBUG mode to aid in determining if the system is experiencing long PCIe
transactions (ie. TLP completion timeouts).

Decreased the maximum latency to from 20 to 12ms
