rockchip: rk3399: Move rockchip_get_cru() out of the driver
This function is called from outside the driver. It should be placed into common SoC code. Move it. Also rename the driver symbol to be more consistent with the other rockchip clock drivers. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
