8530783594 rockchip: video: Add LVDS support in vop driver
LVDS have a different display out mode, add code to get right flag.

The vop_ip decide display device and the remote_vop_id decide which
vop was being used. So we should use the remote_vop_id to set DCLK_VOP.

7b7ad5c31c rockchip: video: Add a video-output driver
Some rockchip SoCs include video output (VOP). Add a driver to support this.
It can output via a display driver (UCLASS_DISPLAY) and currently HDMI and
eDP are supported.

c253948341 rockchip: video: Add a display driver for rockchip HDMI
Some Rockchip SoCs support HDMI output. Add a display driver for this so
that these displays can be used on supported boards.

Unfortunately this driver is not fully functional. It cannot reliably read
EDID information over HDMI. This seems to be due to the clocks being
incorrect - the I2C bus speed appears to be up to 100x slower than the
clock settings indicate. The root cause may be in the clock logic.
