mmc: omap_hsmmc: fix deferred probing
[ 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.
