dt-bindings: extcon: ptn5150: Convert binding to DT schema 

Convert the ptn-5150 extcon driver bindings to DT schema format using
json-schema.  The differences with original bindings document:
 - Use "gpios" suffix for the "int" and "vbus" gpio,
 - Skip generic "pinctrl" property as it is not really required.

* PTN5150 CC (Configuration Channel) Logic device
PTN5150 is a small thin low power CC logic chip supporting the USB Type-C
connector application with CC control logic detection and indication functions.
It is interfaced to the host controller using an I2C interface.
Required properties:
- compatible: should be "nxp,ptn5150"
- reg: specifies the I2C slave address of the device
- int-gpio: should contain a phandle and GPIO specifier for the GPIO pin
connected to the PTN5150's INTB pin.
- vbus-gpio: should contain a phandle and GPIO specifier for the GPIO pin which
is used to control VBUS.
- pinctrl-names : a pinctrl state named "default" must be defined.
- pinctrl-0 : phandle referencing pin configuration of interrupt and vbus
control.
Example:
ptn5150@1d {
compatible = "nxp,ptn5150";
reg = <0x1d>;
int-gpio = <&msmgpio 78 GPIO_ACTIVE_HIGH>;
vbus-gpio = <&msmgpio 148 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&ptn5150_default>;
status = "okay";
};
