power: supply: max17042: support standard shunt-resistor-micro-ohms DT property
shunt-resistor-micro-ohms is a standard property used to describe the
value of a shunt resistor required when measuring currents. Standard
properties should be used instead of vendor-specific ones of similar
intention when possible.
Try to read it from DT, and fall back to the vendor-specific property
maxim,rsns-microohm if unsuccessful for compatibility with existing
DTs.
