[PATCH 34/54] ALSA: sscape: Use standard print API

[Takashi Iwai <tiwai@suse.de>]

Use the standard print API with dev_*() instead of the old house-baked
one.  It gives better information and allows dynamically control of
debug prints.

The device pointer is stored in struct soundscape for calling
dev_*().
