Yes. As Thomas says, if your device is using serial_hds[] directly
it is not user creatable.

The ideal design here is that the device does not touch serial_hds[] at
all, but instead has qdev properties for char devices, which the board
model code wires up based on serial_hds[]. (In this case you could make
them just be alias properties into the escc object that the macio
device creates.)

Either way I don't think there's any reason for the device to be
user-creatable.
