mmc: sunxi: fix deferred probing

The driver overrides the error codes and IRQ0 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. Since commit ce753ad ("platform: finally disallow IRQ0 in platform_get_irq() and its ilk") IRQ0 is no longer returned by those APIs, so we now can safely ignore it...
