Subject: [PATCH v4 2/4] usb: dwc2: add compatible data for rockchip soc

This patch add compatible data for dwc2 controller found on
rk3066, rk3188 and rk3288 processors from rockchip.

Signed-off-by: Kever Yang <kever.yang@...k-chips.com>
Acked-by: Paul Zimmerman <paulz@...opsys.com>

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
