mtd: nand: omap: fix HAM1_SW ecc using default value for ecc.size
Commit "mtd: nand: omap: enable BCH ECC scheme using ELM for generic
platform" (d016dc42cedbf6102e100fa9ecb58462edfb14f8) changed the way
software ECC is configured, both during boot, and during ecc switch, in a way
that is not backwards compatible with older systems:
Older version of omap_gpmc.c always assigned ecc.size = 0 when configuring
for software ecc, relying on nand_scan_tail() to select a default for ecc.size
(256), while the new version of omap_gpmc.c assigns ecc.size = pagesize,
which is likely to not be 256.
Since 1 bit hamming sw ecc is only meant to be used by legacy devices, revert
to the original behavior.
