[PATCH] ASoC: ams-delta: Let the core to register DAPM widgets/routes and controls

[Peter Ujfalusi <peter.ujfalusi@ti.com>]

Pass the DAPM widgets/routes and static controls via the
snd_soc_card struct to core. In this way the machine driver
does not need to handle the DAPM widgets/routes.

Move the setup for initial pin constellation to late_probe
time.
