audio: deprecate -soundhw pcspk

Browse source 
Add deprecation message to the audio init function.

Factor out audio initialization and call that from
both audio init and realize, so setting the audiodev
property is enough to properly initialize pcspk.

Add a property alias to the machine type to set the
audio device, so pcspk can be initialized using:
"-machine pcspk-audiodev=<name>"

Using "-global isa-pcspk.audiodev=<name>" works too but
is not recommended.
