[PATCH v3 1/1] dt-bindings: interrupt-controller: fsl,irqsteer: Add imx8qxp support

[Alexander Stein <alexander.stein@ew.tq-group.com>]

Some SoC like i.MX8QXP use a power-domain for this IP. Add a SoC-specific
compatible, which also requires a power-domain.

Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com>

Thanks for the feedback.

Changes in v3:
* Move 'allOf' before 'additionalProperties'
* Remove superfluous 'minItems: 1'
