RK3399 has two ISPs, but only isp0 was tested.
Add isp0 node in rk3399 dtsi

Verified with:
make ARCH=arm64 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/media/rockchip-isp1.yaml

V3:
- clean up clocks

V2:
- re-order power-domains property

V1:
This patch was originally part of this patchset:

    https://patchwork.kernel.org/patch/10267431/

The only difference is:
- add phy properties
- add ports
