arm64: dts: freescale: imx93-phyboard-nash: Current sense via iio-hwmon

Browse Source 
Commit 21179eae56 ("arm64: dts: freescale: imx93-phyboard-nash: Add
current sense amplifier") added information about the current sensing
circuitry found on the board. Now, lets provide current sense reading
also via IIO-hwmon subsystem. This way, SoM current can be read directly
via sysfs property more conveniently for the customers. No need for them
to manually apply scaling factor calculations anymore.
