[PATCH v5 24/28] hw/audio/pcspk: Remove PCSpkState::migrate field

[Zhao Liu <zhao1.liu@intel.com>]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

The PCSpkState::migrate boolean was only set in the
pc_compat_2_7[] array, via the 'migrate=off' property.
We removed all machines using that array, lets remove
that property, simplifying vmstate_spk[].
