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.
Instead of only checking for -EPROBE_DEFER, propagate all error codes
returned by platform_get_irq_optional() other than -ENXIO, so that
failures are properly reported to the caller.
