[PATCH] mtd: nand: omap: Fix NAND enumeration on 3430 LDP

[Roger Quadros]

In commit 7d5929c1f343 ("mtd: nand: omap: Revert to using software ECC by default"),
we switched back to using 1-bit SW ECC scheme by default. However
commit b491da7233d5 ("mtd: nand: omap: clean-up ecc layout for BCH ecc schemes")
didn't take into account the 1-bit SW scheme (i.e. OMAP_ECC_HAM1_CODE_SW)
when checking for small page devices because it was already got rid of
one commit earlier. Consider OMAP_ECC_HAM1_CODE_SW while deciding
if we can proceed with small page devices or not.

Fixes: 7d5929c1f34 ("mtd: nand: omap: Revert to using software ECC by default")
