Subject: [PATCH v3 1/2] arm64: dts: qcom: sc7280: Add SAR sensors for herobrine

Add nodes for the two SX9324 SAR proximity sensors. Not all herobrine
boards have these sensors, so leave them disabled by default.

Signed-off-by: Matthias Kaehlcke <mka@...omium.org>
---
Depends on 'arm64: dts: qcom: sc7280: Fix sar1_irq_odl node name' [1] for
the second SAR sensor to be probed successfully.
