Subject: [PATCH 1/1] dt-bindings: iio: pressure: Remove vdd-supply and vddio-supply from required list

Some board designs connect vdd and vddio to the system power supply. Remove
these properties from the required list and make them optional, since
drivers/iio/pressure/mpl3115.c does not use them.

Fix below CHECK_DTBS warnings:
arch/arm64/boot/dts/freescale/imx8qm-mek.dtb: pressure-sensor@60 (fsl,mpl3115): 'vdd-supply' is a required property
        from schema $id: http://devicetree.org/schemas/iio/pressure/fsl,mpl3115.yaml#
