soc/amd/picasso: add eMMC MMIO device to devicetree

Add the eMMC MMIO device to the devicetree and make it use the common
AMD eMMC driver. Since there is now a device for this in the devicetree,
also use this device to determine if the FSP should be told if the eMMC
controller is supposed to be disabled.

TEST=On Mandolin the eMMC controller both disappears in the Windows 10
     device manager and in dmesg on Ubuntu 2022.04 LTS
TEST=Morphius with NVMe SSD still works
