Add device nodes for two Maxim max961x current sense amplifiers
sensing the VDD_0.8V and DVFS_0.8V lines.
Based on a patch for r8a7796-salvator-x.dts by Jacopo Mondi.
Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>

Bindings and driver are now in staging-next.
v2:
- Use shunt-resistor-micro-ohms to match updated bindings.
