Subject: [PATCH v1 10/14] arm64: dts: imx8mq-librem5: Adjust proximity sensor's near levels

From: Sebastian Krzyszkowiak <sebastian.krzyszkowiak@...i.sm>

Based on tests with my left ear (which appears to require lower levels
than the right one), one Birch, one Dogwood and three Evergreens.

It seems that the sensor reacts very weakly to hair, so let's make
the thresholds rather generous to compensate.
