[PATCH nvmem 1/1] nvmem: imx: correct the fuse word index

[fugang . duan]

From: Fugang Duan <fugang.duan@xxxxxxx>

iMX8 fuse word index represent as one 4-bytes word,
it should not be divided by 4.

Exp:
- MAC0 address layout in fuse:
offset 708: MAC[3] MAC[2] MAC[1] MAC[0]
offset 709: XX     xx     MAC[5] MAC[4]
