This patch implements functionality of following ioctl:

SNDRV_TIMER_IOCTL_TREAD - Setting enhanced time read

    Sets enhanced time read which is used for reading time with timestamps
    and events. The third ioctl's argument is a pointer to an 'int'. Enhanced
    reading is set if the third argument is different than 0, otherwise normal
    time reading is set.

Implementation notes:

    Because the implemented ioctl has 'int' as its third argument, the
    implementation was straightforward.
