Subject: [PATCH] spi: fsl: use platform_get_irq() instead of
 of_irq_to_resource()

commit 63aa6a692595d47a0785297b481072086b9272d2 upstream.

Unlike irq_of_parse_and_map() which has a dummy definition on SPARC,
of_irq_to_resource() hasn't.

But as platform_get_irq() can be used instead and is generic, use it.
