This change does 3 things at once:
- documents the recently added "fsl,extirq-map" property, which replaces
"interrupt-map"
- clarifies the format of the property whose name is changing
- hides the "interrupt-map" property, that the driver still supports for
backwards compatibility reasons, although not for long.
