Subject: [PATCH net-next v2 2/6] dt-bindings: net: tsnep: Allow additional interrupts

Additional TX/RX queue pairs require dedicated interrupts. Extend
binding with additional interrupts.

+      it is assumed that this interrupt is the "mac" interrupt.
+      "txrx-[1-7]" are the interrupts for additional TX/RX queue pairs.
