Hm, that rings a bell. The MMC controller is located below
root port 0000:00:1c.0, which has vendor/device ID 8086:8c10.
We're having trouble with the exact same root port on 2015
MacBook Pros where it mysteriously prevents them from powering off:

Does this help:
echo on > /sys/bus/pci/devices/0000:00:1c.0/power/control
Thanks,
Lukas
