arm64: dts: rockchip: Increase VOP clk rate on RK3328
[ Upstream commit 0f2ddb128fa20f8441d903285632f2c69e90fae1 ]
The VOP on RK3328 needs to run at a higher rate in order to produce a
proper 3840x2160 signal.
Change to use 300MHz for VIO clk and 400MHz for VOP clk, same rates used
by vendor 4.4 kernel.
