[PATCH RFC 07/13] mmc: owl: fix deferred probing

[Sergey Shtylyov]

The driver overrides the error codes returned by platform_get_irq() to
-EINVAL, 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: ff65ffe46d28 ("mmc: Add Actions Semi Owl SoCs SD/MMC driver")
