[PATCH 3/3] omap : nand : fix subpage ecc issue with prefetch

[Bryan DE FARIA]

When reading a subpage with a non dividable by 4 ecc number of byte, the
prefetch function gets first the extra bytes, then reads the bytes lefting.
Extra bytes are not returned in the buffer (they are overwritten), which makes
the software ecc fail.
