[PATCH 3/3] arm64: dts: imx8mn: Use single port for ISI

[Alexander Stein <alexander.stein@xxxxxxxxxxxxxxx>]

The ISI on i.MX8M Nano only has one port/channel, so use the single port
node. Fixes the DTBS_CHECK warning:
/soc@0/bus@32c00000/isi@32e20000/ports: graph node has single child node
'port@0', #address-cells/#size-cells are not necessary
