Takashi Sakamoto 5422835666 ALSA: ctl: remove unused macro for timestamping of elem_value 
In a former commit, 'tstamp' member was removed from 'struct
snd_ctl_elem_value' in a middle way toward solution of Y2038 issue. In a
protocol of ALSA control interface, this member is designed to deliver
timestamp information in the value structure when the target element
supports SNDRV_CTL_ELEM_ACCESS_TIMESTAMP flag.

Actually, the feature is neither used by kernel space nor user space,
especiall alsa-lib has no API for the feature. Therefore it's reasonable
to remove both of them. Practically, the timestamp information
corresponds to no information about type of clock ID. It can bring
confusions to applications.
