rk3066, rk3188 and rk3288 processors from rockchip.

Changes in v5:
- max_transfer_size change to 65535 to met the requirement of
  header file

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
