MLK-12623-03 ARM: imx: Add cpu speed grading check for imx6ul

In the OCOTP fuse map, the speed grading[1:0] define the MAX
CPU speed the chip can run. The detailed definition is below:
2b'00: Reserved;
2b'01: 528000000Hz;
2b'10: 696000000Hz;
2b'11: Reserved;

We need to disable the illegal setpoints according to the fuse map.
