ALSA: asihpi - Rewrite PCM timer function. Update control names.
Reported samples_played from card may be inaccurate, so don't use it. Update control names to be closer to alsa standard practice. Also fixed some accidentally lowercased strings. [Removed adriver.h inclusion for external module builds by tiwai] Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
