This does not look right for the IRQ. Please add it to the irqs.h and 34xx,
then set it dynamically during the init just like we handle the other
interrupt numbers.

This is because the irq numbers can change between omaps, like irqs-44xx.h
already has

#define OMAP44XX_IRQ_GPMC                       (20 + OMAP44XX_IRQ_GIC_START)

These should probably be OMAP_NAND_IO_READ and OMAP_NAND_IO_WRITE?
