usb: chipidea: ci_hdrc_imx: Propagate errors from optional IRQ lookup
platform_get_irq_optional() returns a positive IRQ number on success or
a negative error code on failure. For an optional IRQ, -ENXIO indicates
that no IRQ is available, while other errors should be propagated.
Propagate errors such as -EPROBE_DEFER and -EINVAL instead of continuing
probe without the IRQ.
