dt-bindings:iio:pressure:murata,zpa2326 yaml conversion

Simple conversion with a few minor tweaks:
* I added 1MHz max for spi-max-frequency
* I have give myself as the maintainer.  This driver was written by
  Gregor Boirie but I don't have an up to date email address for Gregor.

-Murata ZPA2326 pressure sensor
-
-Pressure sensor from Murata with SPI and I2C bus interfaces.
-
-Required properties:
-- compatible: "murata,zpa2326"
-- reg: the I2C address or SPI chip select the device will respond to
-
-Recommended properties for SPI bus usage:
-- spi-max-frequency: maximum SPI bus frequency as documented in
-  Documentation/devicetree/bindings/spi/spi-bus.txt
-
-Optional properties:
-- vref-supply: an optional regulator that needs to be on to provide VREF
-  power to the sensor
-- vdd-supply: an optional regulator that needs to be on to provide VDD
-  power to the sensor
-- interrupts: interrupt mapping for IRQ as documented in
-  Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-
-Example:
-
-zpa2326@5c {
-	compatible = "murata,zpa2326";
-	reg = <0x5c>;
-	interrupt-parent = <&gpio>;
-	interrupts = <12>;
-	vdd-supply = <&ldo_1v8_gnss>;
