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

[ 0=2E014234] irq: no irq domain found for interrupt-controller@10200100 !
[ 0=2E020981] Failed to map interrupt for /timer@10008000
[ 0=2E026248] Failed to initialize '/timer@10008000': -22
[ 4=2E314126] 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
