mmc: omap_hsmmc: fix deferred probing

BugLink: https://bugs.launchpad.net/bugs/2033931
[ Upstream commit fb51b74a57859b707c3e8055ed0c25a7ca4f6a29 ]

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.
