clk: rockchip: rk3368: fix parents of video encoder/decoder

commit 0f28d98463498c61c61a38aacbf9f69e92e85e9d upstream.

The vdpu and vepu clocks can also be parented to the npll and current
parent list also is wrong as it would use the npll as "usbphy" source,
so adapt the parent to the correct one.
