ARM: dts: rockchip: add cpu and gpu regulators to rk3288-evb-act8846
The evaluation board using the act8846 as main pmic uses two additional regulators to provide the cpu and gpu voltage. Add these and also add the link to cpu supply from vdd_cpu. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Tested-by: Daniel Lezcano <daniel.lezcano@linaro.org>
