Subject: 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.
