The drive_shift can have values as 0 to 3. The value "0" means degree 0, "1" means degree 90, "2" means degree 180 and "3" means degree 270. 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 is sometimes eMMC read fail during booting, and it occured because of end-bit error. This patch solves it.
