mmc: pci_mmc: Only generate ACPI code for the SD card

Browse source 
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.
