    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.
