arm64: dts: freescale: imx93-phyboard-nash: Add current sense amplifier
There is a current sensing circuitry on the phyBOARD-Nash-i.MX93 capable
of measuring input current consumption of the phyCORE-i.MX93 SoM @ 3.3V.
Circuity consists of MAX4372 current-sense amplifier (50V/V) with two 70
mOhm shunts resistors in parallel configuration (effective R = 35 mOhm)
connected to the SoC internal 12-bit ADC channel #1 (Vref = 1.8V) via
voltage divider with ratio of 1/2. This results in a current scaling
factor of 0.502232142 mA/LSB.
