Is this part of SoC? If so, then SoC compatibles are preferred, not IP
block versions.
We have the same IP on different chips. So no, it isn't tied to a specific SoC.

Use proper defines for flags.
Not understanding this comment. Can you elaborate?
I believe Krzysztof would prefer that you use:
interrupts = <GIC_SPI 0x33 IRQ_TYPE_LEVEL_HIGH>
here, which would require using defined from
include/dt-bindings/interrupt-controller/{arm-gic.h,irq.h}
