[PATCH/RFC 4/6] staging: board: kzm9d: Translate hwirq numbers to virq numbers

As of commit 9a1091ef0017c40a ("irqchip: gic: Support hierarchy irq
domain."), GIC IRQ numbers are virtual, breaking hardcoded hardware IRQ
numbers in platform device resources.

Translate the hardware IRQ numbers to virtual IRQ numbers to fix this.

Untested due to lack of hardware
