mmc: mvsdio: fix deferred probing

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

Fixes: 9ec36ca ("of/irq: do irq resolution in platform_get_irq")
