Subject: [PATCH v2 1/2] dt-bindings: media: cdns,csi2rx.yaml: Add optional interrupts for cdns-csi2rx

The Cadence CSI2RX IP exposes 3 interrupts [0] 12.7 camera subsystem.
Enabling these interrupts will provide additional information about a CSI
packet or an individual frame. So, add support for optional interrupts
and interrupt-names properties.
