mtd: nand: mxc: Fix failed/corrected values

[Sascha Hauer]

The mxc_nand controller returns bogus corrected/failed values. Fix
this by adding a own read_page function. The other two patches
are cleanups based on the first one. The patches are targeted for
the v2/v3 controller types, we could do the same for v1 controllers
aswell, but I left that out because I don't have any hardware handy
at the moment.
