dt-bindings: net: pse-pd: ti,tps23881: Add interrupt description

Add an interrupt property to the device tree bindings for the TI TPS23881
PSE controller. The interrupt is primarily used to detect classification
and disconnection events, which are essential for managing the PSE
controller in compliance with the PoE standard.

Interrupt support is essential for the proper functioning of the TPS23881
controller. Without it, after a power-on (PWON), the controller will
no longer perform detection and classification. This could lead to
potential hazards, such as connecting a non-PoE device after a PoE device,
which might result in magic smoke.
