drm/rockchip: vop: add a series of vop support

Vop Full framework now has following vops:
IP version    chipname
  3.1           rk3288
  3.2           rk3368
  3.4           rk3366
  3.5           rk3399 big
  3.6           rk3399 lit
  3.7           rk3228
  3.8           rk3328

The above IP version is from H/W define, some of vop support get
the IP version from VERSION_INFO register, some are not.
hardcode the IP version for each vop to identify them.

major version: used for IP structure, Vop full framework is 3,
               vop little framework is 2.
minor version: on same structure, newer design vop will bigger
               then old one.
