i didn't noticed before that everything except of the interrupts are
identical to the bcm283x boards [1]. So please define both nodes in
bcm283x.dtsi (with bcm283x interrupts) and just override the interrupts
for bcm2711 in this dtsi file.

As a result the clocks and power domains from above can go to
bcm2835-rpi.dtsi.
