Rockchip processors rk3066, rk3188 and rk3288,
and enable dts for rk3288 evb.

Changes in v4:
- max_transfer_size change to 65536, this should be enough

  to 0x7ffff which may make dma_alloc_coherent fail when
  non-dword aligned buf from driver like usbnet happen.
- remove EHCI and HSIC dts patch for Doug had post it seprately.

Changes in v3:
- EHCI and HSIC move new for version 3.
