[ALSA] PCM interface - rename SNDRV_PCM_TSTAMP_MMAP to SNDRV_PCM_TSTAMP_ENABLE
Change semantics for SNDRV_PCM_TSTAMP_MMAP. Doing timestamping only in the interrupt handler might cause that hw_ptr is not related to actual timestamp. With this change, grab timestamp at every hw_ptr update to have always valid timestamp + ring buffer position pair. With this change, SNDRV_PCM_TSTAMP_MMAP was renamed to SNDRV_PCM_TSTAMP_ENABLE. It's no regression (I think). Signed-off-by: Jaroslav Kysela <perex@perex.cz>
