Takashi Iwai ee5f85d929 ALSA: hda: Add codec on bus address table lately

The call of snd_hdac_bus_add_device() is needed only for registering
the codec onto the bus caddr_tbl[] that is referred essentially only
in the unsol event handler.  That is, the reason of this call and the
release by the counter-part function snd_hdac_bus_remove_device() is
just to assure that the unsol event gets notified to the codec.

But the current implementation of the unsol notification wouldn't work
properly when the codec is still in a premature init state.  So this
patch tries to work around it by delaying the caddr_tbl[] registration
at the point of snd_hdac_device_register().

Also, the order of snd_hdac_bus_remove_device() and device_del() calls
are shuffled to make sure that the unsol event is masked before
deleting the device.
