ARM: imx: Remove imx_add_imx_dma() unused irq_err argument

No callers of imx_add_imx_dma() need an error IRQ, so they supply 0 as
"irq_err", which means we register a resource of IRQ 0, which is invalid
and causes a warning if used.

Remove the "irq_err" argument altogether so there's no chance of trying to
use the invalid IRQ 0.

Fixes: a85a6c86 ("driver core: platform: Clarify that IRQ 0 is invalid")
