staging: bcm2835-audio: Set SNDRV_PCM_INFO_SYNC_APPLPTR 



commit b59d6a5f73501f74848d6700101e7736afe3d54a upstream.

The recent ALSA PCM core supports the SNDRV_PCM_INFO_SYNC_APPLPTR flag
indicating that the driver needs the ack call at each appl_ptr
update.  This is requirement for the indirect PCM implementations like
bcm2835-audio driver, too.
