Pyun YongHyeon 48630d79c5 If the maximum payload size is 256 bytes or more, set the DMA write ...

water mark to 256 bytes.  Otherwise controller will encounter DMA
write under run errors and would result in RX DMA hang. If the
maximum payload size is 128 bytes, the water mark is set to 128
bytes as usual.
While here, set maximum read request size to 2048 for BCM5719/BCM5720.
For other PCIe devices, use 4096. And reprogram the maximum read
request size whenever device reset is performed.
