This determines whether the Apple Sound Chip (ASC) is set to enhanced mode

Adding this as a machine parameter allows QEMU to be used as an developer aid
for testing and migrating code from ASC to EASC.

Is the getter useful? Otherwise:
Isn't it a requirement? Otherwise I can see that if we decide to enumerate machine properties
(similar as to how device properties appear in "info qtree") then it would be impossible
to display its value. Certainly at the moment we consider that adding an object property to an
underlying struct effectively makes it "public".
Just FYI this is not a requirement, per "qom/object.h":
/**
* object_property_add_bool:
* @obj: the object to add a property to
* @name: the name of the property
* @get: the getter or NULL if the property is write-only.
* @set: the setter or NULL if the property is read-only
I'm not sure when we want a write-only QOM boolean property, so I
genuinely ask, since I agree introspecting QOM object fields from
the monitor is helpful.
