[PULL 20/31] cpu: Move AVR target vmsd field from CPUClass to DeviceClass

[Richard Henderson <richard.henderson@linaro.org>]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

See rationale in previous commit. Targets should use the vmsd field
of DeviceClass, not CPUClass. As migration is not important on the
AVR target, break the migration compatibility and set the DeviceClass
vmsd field. To feel safer, increment the vmstate version.
