[PATCH] mtd: spi-nor: winbond: fix w25q128 regression

Commit 83e824a4a595 ("mtd: spi-nor: Correct flags for Winbond w25q128")
removed the flags for non-SFDP devices. It was assumed that it wasn't in
use anymore. This turned out to be wrong. Add the no_sfdp_flags as
well as the size again.

Hartmut, Linus, could you please test it on your boards? Also, do
you have a real name we should put in the Reported-by tag?

This will also need a manual backport to the stable kernels due to
the new syntax. But that should be straight forward.
