From: Joe Schaack <jscha...@xes-inc.com>
Modify the nand_davinci_write_page() function to use ECC when appropriate
to verify writes. Previously if a single bit error occured and software
ECC was used the write verification would report a failure. However,
the write really did succeed, since ECC can handle the error.

I don't have davinci hardware to test on, but the change should
mirror the nand_base.c change.
