mmc: mvsdio: fix deferred probing

[ Upstream commit 8d84064da0d4672e74f984e8710f27881137472c ]

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.
