dt-bindings:iio:pressure:hoperf,hp03 yaml conversion

One quirk in the txt file was that the xclr gpio was specified as
xclr-gpio rather than xclr-gpios. I've fixed that in the
yaml version.

-Required properties:
-- compatible: must be "hoperf,hp03"
-- xclr-gpio: must be device tree identifier of the XCLR pin.
-             The XCLR pin is a reset of the ADC in the chip,
-             it must be pulled HI before the conversion and
-             readout of the value from the ADC registers and
-             pulled LO afterward.
-
-Example:
-
-hp03@77 {
-	compatible = "hoperf,hp03";
-	reg = <0x77>;
-	xclr-gpio = <&portc 0 0x0>;
-};
