Similar to DCLK_LCDC on RK3328, the DCLK_VOP on RK3228 is typically
parented by the hdmiphy clk and it is expected that the DCLK_VOP and
hdmiphy clk rate are kept in sync.

Use CLK_SET_RATE_PARENT and CLK_SET_RATE_NO_REPARENT flags, same as used
on RK3328, to make full use of all possible supported display modes.

Fixes: 307a2e9ac524 ("clk: rockchip: add clock controller for rk3228")
