arm64: dts: ti: k3-j721s2: Fix the interrupt ranges property for main & wkup gpio intr

The parent's input irq number is wrongly subtracted with 32 instead of
using the exact numbers in:

https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/j721s2/interrupt_cfg.html



The GPIO interrupts are not working because of that. The toggling works
fine but interrupts are not firing. Fix the parent's input irq that
specifies the base for parent irq.

Tested for MAIN_GPIO0_6 interrupt on the j721s2 EVM.
