arm64: dts: rockchip: define cpu-supply on the

Commit-Message
The TS433 seems to use a silergy,syr827 regulator for the cpu supply. At least that is the compatible used in the vendor devicetree, though it could very well also be another fan53555 clone. Define the needed regulator node and hook up the cpu-supply to the cpu cores. Tested-by: Uwe Kleine-König <ukleinek@...> Signed-off-by: Heiko Stuebner <heiko@...>
