Well if you read the message you reference it states: "So add a module parameter to enable pmp usage, and default this to off, so that directly attached disks keep working normally." So it seems if you use a multiple you need to do a different option than without so it indicates it would need it. If you do "modinfo ahci_sunxi" you'll see that actually the patch has landed and there is a enable_pmp parameter. So you'll need to create something like /etc/modprobe.d/sunxi.conf and add a line "options ahci_sunxi enable_pmp=1" line (no I've not verified that is correct so you'll need to check it) and reboot.
