mtd: gpmi: fix ECC regression
The "legacy" ECC layout used until 3.12-rc1 uses all the OOB area by
computing the ECC strength and ECC step size ourselves.
Commit 2febcdf84b
("mtd: gpmi: set the BCHs geometry with the ecc info")
makes the driver use the ECC info (ECC strength and ECC step size)
provided by the MTD code, and creates a different NAND ECC layout
for the BCH, and use the new ECC layout. This causes a regression:
We can not mount the ubifs which was created by the old NAND ECC layout.
This patch fixes this issue by reverting to the legacy ECC layout.
We will probably introduce a new device-tree property to indicate that
the new ECC layout can be used. For now though, for the imminent 3.12
release, we just unconditionally revert to the 3.11 behaviour.
This leaves a harmless cosmetic warning about an unused function. At
this point in the cycle I really don't care.
