[PATCH 2/5] arm64: dts: imx8ulp: Add CSI and ISI Nodes

[guoniu . zhou]

From: Guoniu Zhou <guoniu.zhou@xxxxxxx>

The CSI-2 in the i.MX8ULP is almost identical to the version present
in the i.MX8QXP/QM and is routed to the ISI. Add both the ISI and CSI
nodes and mark them as disabled by default since capture is dependent
on an attached camera.
