Replace direct NVIC pending-state calls with k_irq_set_pending()/
k_irq_is_pending()/k_irq_clear_pending(), dropping the dependency on
cmsis_core.h where nothing else needed it.
This driver called the arm_gic_irq_* pending helpers directly; the
portable API removes the GIC-specific dependency. The gic.h include
stays for GIC_SPI_INT_BASE.
