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]
