The OOB size of the SK Hynix H27UCG8T2BTR is currently detected to be
640 bytes, while the datasheet states that it should be 1280 bytes.

I only have one single device with a SK Hynix NAND flash, so I cannot
say whether this fix may or may not break other chips. other datasheets
I have checked:
- H27UBG8T2B uses a page size of 8KiB -> not applicable
- H27UBG8T2A also uses a page size of 8KiB -> not applicable either

so I would appreciate if someone else could confirm (even if it's
"just" by looking at a datasheet) that this patch should work for other
SK Hynix NAND chips with 16KiB page size.

I decided not to add a "Fixes" tag because it seems H27UCG8T2BTR was
not supported properly at any point in the past (upstream at least).
