Zhang Rui 80bbadbc42 mmc: sdhci-acpi: support deferred probe 
commit e28d6f0487 upstream.

With commit 67bf5156ed ("gpio / ACPI: fix returned error from
acpi_dev_gpio_irq_get()"), mmc_gpiod_request_cd() returns -EPROBE_DEFER if
GPIO is not ready when sdhci-acpi driver is probed, and sdhci-acpi driver
should be probed again later in this case.

This fixes an order issue when both GPIO and sdhci-acpi drivers are built
as modules.
