mmc: mtk-sd: fix deferred probing
[ Upstream commit 0c4dc0f054891a2cbde0426b0c0fdf232d89f47f ]
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.
