MLK-12852 ocotp: mxc: mx6ull: fix GP3/GP4 prog 

Bank 7 and Bank 8 only supports 4 words each. 'bank << 3 | word'
is not correct when program bank 8, since ocotp controller actully
use word index.

For example: fuse prog 8 3 1; The word index is (8 << 3 | 3) --> 67.
But actully it should be (7 << 3 | 7) ---> 63.
So fix it.
