This is a revert of 93b4f4050^ and 93b4f4050.
For a SpiceCharDeviceInstance, the base interface must be a
SpiceCharDeviceInterface instance, not a SpiceBaseInterface instance, or
spice-server code will end up reading out of bounds.
vmc_state/vmc_write/vmc_read implementations also have to be provided.
