Changes in v4:
- max_transfer_size change to 65536, this should be enough
for most transfer, the hardware auto-detect will set this
to 0x7ffff which may make dma_alloc_coherent fail when
non-dword aligned buf from driver like usbnet happen.
Changes in v3: None
Changes in v2:
- set most parameters as driver auto-detect
