[PATCH] rk3399: Add four clocks to clock driver needed by framebuffer

[Wolfram Joost]

This patch adds the four clock gates

- ACLK_VOP0
- ACLK_VOP1
- HCLK_VOP0
- HCLK_VOP1

to the rockchip rk3399 clock drivers.

These clock gates were referenced by arch/arm/dts/rk3399.dtsi for
vopb and vopl.

The driver drivers/video/rockchip/rk3399_vop.c won't get probed
without these clocks and the framebuffer does not work.
