This is required for linux-6.1 compatibility.
IRQs are not automatically mapped from HW to virtual IRQ numbers when
the IRQ domain is registered. This happens when the IRQ number is read
from the device tree based on the IRQ domain from the device tree now.
In kernel 5.15 it was done when the IRQ domain was registered.
