soc/amd/cezanne,common: expose eMMC device in ACPI when enabled
When the eMMC MMIO device is enabled in the devicetree, it needs to be exposed in ACPI in order for the OS driver to be able to attach to it. The Cezanne eMMC controller isn't used in google/guybrush, so this the code path where the eMMC MMIO device is enabled in the devicetree can't be easily tested.
