WM8753 datasheet (p89) explicitly goes through the steps to power stuff
down without pops (was reading this yesterday), but it didn't bank on an
external amp in the way.  You're meant to disable the output pins and
then kill Vref, then pull power.  I guess we should do that and then
disable the external amp.  I'll have a go at it.
