These series patches is to add some new format supported by some rockchip
socs, include:
  RK3288/RK3228/RK3328/RK3368/RK3399

these new format layout as following rule:
2 plane YCbCr
  index 0 = Y plane, Y3:Y2:Y1:Y0 10:10:10:10
  index 1 = Cb:Cr plane, Cb3:Cr3:Cb2:Cr2:Cb1:Cr1:Cb0:Cr0 10:10:10:10:10:10:10:10
  or
  index 1 = Cr:Cb plane, Cr3:Cb3:Cr2:Cb2:Cr1:Cb1:Cr0:Cb0 10:10:10:10:10:10:10:10

v2:
  1. add describe for new format;
  2. use block formats to describe new format;

  drm/rockchip: Add vop_format_get_bpp to get format bpp
  drm/rockchip: Add support 10bit yuv format
