The drive_shift can have from 0 to 3 values. The meanings of the values are degree of the phase shifted clock. 0: 0 degree phase shifted clock 1: 90 degree phase shifted clock 2: 180 degree phase shifted clock 3: 270 degree phase shifted clock In the same as drive_shift, the sample_shift can have values as 0 to 3. The meanings of values are also the same. There are sometimes fastboot fail with some targets, and this patch solves it.
