mmc: usdhi60rol0: fix deferred probing 

[ Upstream commit 413db49973 ]

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: 9ec36cafe4 ("of/irq: do irq resolution in platform_get_irq")
