mtd: nand: mxc: Fix failed/corrected values for v1 controllers
The v1 controller code has several flaws:
- We do not forward the number of corrected bitflips to the upper layers
- For 2k page NAND chips only the status results from the fourth subpage
read are evaluated, so ECC failures in the other subpages remain
uncovered
- When there are uncorrectable errors we have to increase the statistics
counter, but still have to return successfully. Currently we return
an error
This patch fixes this by introducing a v1 specific read_page function.
