MLK-11159-2 Revert "MLK-11028 imx: mx6qp change L2 prefetch offset to 0"
This reverts commit 2bc93d766dee5d5dc33035446f82622c4f1fb784.
After further investigation, find L2 prefetch offset setting of 0xF is not the
root cause for USB stress reboot failure. With the fix in USB driver,
and L2 prefetch offset setting of 0xF, the reboot stress test has passed 4-days
both on imx6q and imx6qp sabreauto board.
