The VOP2 is found on newer Rockchip SoCs like the rk3568 or the rk3566. The binding differs slightly from the existing VOP binding, so add a new binding file for it.

Notes: Changes since v11: - Document "vop" and "gamma-lut" reg-names property - make reg-names mandatory for VOP2
Changes since v5: - Add Robs Reviewed-by:
Changes since v4: - Fix clk names in example - Drop unnecessary assigned-clocks, assigned-clock-rates and assigned-clock-parents
Changes since v3: - drop redundant _vop suffix from clock names
Changes since v3: - new patch
