[PATCH] arm64: dts: r8a7795: salvator-x: Add current sense amplifiers

[Geert Uytterhoeven]

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 at glider.be>

Pending acceptance of the maxim,max9611 DT bindings.
