with Patch "irqchip: Fix probing deferal when using IRQCHIP_PLATFORM_DRIVER helper" i can boot my board, but i get these errors:

[ 0.014234] irq: no irq domain found for interrupt-controller@...00100 !
[ 0.020981] Failed to map interrupt for /timer@...08000
[ 0.026248] Failed to initialize '/timer@...08000': -22
[ 4.314126] hw perfevents: /pmu: failed to register PMU devices!

if i revert f97dbf48ca43009e8b8bcdf07f47fc9f06149b36 these are gone

So from my pov revert is best way at the moment
