Subject: [PATCH v2 02/13] dt-bindings: extcon: ptn5150: Use generic "interrupts" property

Interrupts do not have to be always GPIO based so instead of expecting
"int-gpios" property and converting the GPIO to an interrupt, just
accept any interrupt via generic "interrupts" property.

Mark the old "int-gpios" as deprecated.
