ALSA: Replace timespec with timespec64
Since timespec is not year 2038 safe on 32bit system, and we need to convert all timespec variables to timespec64 type for sound subsystem. This patch is used to do preparation for following patches, that will convert all structures defined in uapi/sound/asound.h to use 64-bit time_t.
