This is the remaining part of Martin's patches to remove the deprecations
connected to audio backend configuration.  With these patches, all sound
cards have to be configured with an audio backend; only embedded cards
get the luxury of a default backend that emits or records no audio at all.
Fortunately, this is easy to do with the existing "-audio" option.

Apart from some rebasing changes, the changes are:

- the "-M" option for the embedded audiodev is only added to machines
  that need it, and renamed from "default-audiodev" to just "audiodev".

- the embedded audiodev is also accessible by specifying "-audio DRIVER"
  without a model

- the audiodev option is also configurable with -readconfig

- MIPS fuloong2e and PPC pegasos2 need changes in order to expose
  the embedded audiodev, too
