mmc: sdhci-acpi: fix deferred probing

[ Upstream commit b465dea5e1540c7d7b5211adaf94926980d3014b ]

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.
