[ Upstream commit f34c6e6257aa477cdfe7e9bbbecd3c5648ecda69 ]

Since commit 9ec36cafe43b ("of/irq: do irq resolution in platform_get_irq")
platform_get_irq() can return -EPROBE_DEFER. However, the driver overrides
an error returned by that function with -ENOENT which breaks the deferred
probing. Propagate upstream an error code returned by platform_get_irq()
and remove the bogus "platform" from the error message, while at it...
