kernel: fix DMA error when BCM4331 is connected to BCM4706
The BCM4331 supports a PCIe max request size of 512 bytes and uses that, but the PCIe controller in the BCM4706 just supports 128 Bytes and that causes a DMA error for packages bigger than 126 bytes. This fixes the problem by setting the BCM4331 also to 128 Bytes. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 37709
