Since these board functions seem to be the same for all boards which use FSP, move them into a common file. We can adjust this later if future FSPs need more flexibility.
This creates a generic PCI MMC device.

Changes in v2: - Move MMC code into a new pci_mmc.c file - Remove setup_early_uart() function prototype
