Subject: [PATCH 09/10] ARM: dts: rockchip: add vdec node for RK322x

The vdec IP block of RK322x is the same as RK3399 has and the driver can
be used as-is.

Add the respective node to the device tree.

Note: core and cabac clock need to be set to a specific rate which is
done by using "assigned-clocks" / "assigned-clock-rates" properties
(axi clock rate is currently set in the driver).
