drm/rockchip: dw-dp: optimeize disable/enable dp flow

Browse Source 
when enable dp, it need config as follow:
1. enable dp link clk;
2. config dp regs;
3. enable dp video stream;
4. enable vop data stream.
when disable dp, it need config as follow:
1. disable vop data steam.
2. disable dp video stream;
3. disable dp link clk.
