AMD has more drivers will use ACPI to platform bus driver later,
all those devices need iommu support, such as eMMC acpi driver.

Is the platform_bus_type always defined or does this code needs to be
guarded by another ifdef?
Joerg,
Currently, Only New eMMC driver will rely on this sdhci-acpi.c, but I
could not find a suitable ifdef XXX micro to limit this
platform_bus_type here like AMBA bus type before.
Do you think this MMC_SDHCI_ACPI is ok?
Vincent.
