mmc: pci_mmc: Only generate ACPI code for the SD card
At present if an eMMC part is in the system, the ACPI table generated will include information about that, as well as the SD card. We only need to include the SD card, since it has a card-detect GPIO. Use a different compatible string for each option, and add code only for the SD card.
