bayleybay_fsp: Add comments for the MMC/SD devices in devicetree

This just adds some additional comments for the EMMC / SD / SDIO PCI
devices in devicetree.

The documentation states that the EMMC 4.1 device shouldn't be used,
but it's available to enable in the FSP.  Because it can be enabled,
I've included it in the devicetree even though its use is discouraged.
