drm/rockchip: vop2: add more color bar mode support

Browse Source 
Color bar mode usage instructions:

  Enable horizontal color bar:
      echo 1 > /sys/kernel/debug/dri/0/video_port0/color_bar
  Enable vertical color bar:
      echo 2 > /sys/kernel/debug/dri/0/video_port0/color_bar
  Enable horizontal color gradient:
      echo 3 > /sys/kernel/debug/dri/0/video_port0/color_bar
  Enable vertical color gradient:
      echo 4 > /sys/kernel/debug/dri/0/video_port0/color_bar
  Enable mutant color:
      echo 5 > /sys/kernel/debug/dri/0/video_port0/color_bar
  Enable fix black color:
      echo 6 > /sys/kernel/debug/dri/0/video_port0/color_bar
  Enable fix white color:
      echo 7 > /sys/kernel/debug/dri/0/video_port0/color_bar
  Disable color bar:
      echo 0 > /sys/kernel/debug/dri/0/video_port0/color_bar
