ALSA: Avoid using timespec for struct snd_ctl_elem_value
The struct snd_ctl_elem_value will use 'timespec' type variables to record timestamp, which is not year 2038 safe on 32bits system. Since there are no drivers will implemented the tstamp member of the struct snd_ctl_elem_value, and also the stucture size will not be changed if we change timespec to s64 for tstamp member of struct snd_ctl_elem_value. From Takashi's comments, "In the library, applications are not expected to access to this structure directly. The applications get opaque pointer to the structure and must use any control APIs to operate it. Actually the library produce no API to handle 'struct snd_ctl_elem_value.tstamp'. This means that we can drop this member from alsa-lib without decline of functionality." Thus we can simply remove the tstamp member to avoid using the type which is not year 2038 safe on 32bits system.
