mmc: sh_mmcif: fix deferred probing
[ Upstream commit 5b067d7f855c61df7f8e2e8ccbcee133c282415e ]
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.
