arm64: dts: rockchip: Enable IRQ mode for fiq-debugger on RV1126B

Browse Source 
Switch the fiq-debugger driver to use IRQ mode instead of FIQ mode on
RV1126B platforms. This change is necessary because:

1. The Trust Zone implementation of fiq-debugger is still under validation
2. IRQ mode provides more stable operation during early bring-up
3. Prevents potential system instability from FIQ handling conflicts
