x86: mmc: Move common FSP functions into a common file
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. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>
