[PATCH] [MTD] Make ecclayout static const

[Kyungmin Park]

There's missing one in OneNAND.

After changint "static const" If we only check the free->length, it can
point beyond the ecclayout->oobfree. Since it casts the free pointer and
only check length.
If we only check the array_size, it mis-calculate the readcol & readend in
1KB page OneNAND
So we have to check both array_size and free->length.

for (i = 0; i < ARRAY_SIZE(this->ecclayout->oobfree) && free->length; i++,
free++)

Same as above

After previous mail comments. I will post it again.

Thank you,
