The VOP2 is the display output controller on the RK3568. Add the node
for it to the dtsi file along with the required display-subsystem node
and the iommu node.

Notes:
    Changes since v4:
    - Add Robs Ack
    
    Changes since v3:
    - Bring back gamma_lut regs
    - Drop redundant _vop suffix from clock names

One thing I missed to log in the changelog: These defines now have a
ROCKCHIP_ prefix rather than a RK3568_ prefix so that they can be reused
by future SoCs. Also I start counting from one now so that a zero
initialized variable becomes an invalid value.
