[PATCH v3 12/12] mmc: usdhi60rol0: fix deferred probing

[Sergey Shtylyov <s.shtylyov@omp.ru>]

The driver overrides the error codes returned by platform_get_irq_byname()
to -ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing.  Switch to propagating error
codes upstream.

Fixes: 9ec36cafe43b ("of/irq: do irq resolution in platform_get_irq")
