Subject: [PATCH] ARM: dts: imx6dl-b1x5v2: drop unsupported vcc-supply for MPL3115A2

The MPL3115A2 I2C pressure sensor driver does not take a VCC regulator.
The bindings are so far trivial, but the datasheet does not have a VCC
pin.

FWIW &reg_3v3_acm is connected to VDD obviously, but it's an
always-on regulator without any means to control it, so there
is no need to describe it.

Applied, thanks!
