[MTD] [NOR] Fixup for incorrect CFI data in Spansion S29GL064/32N flash chips

This is a known erratum confirmed by Spansion.  I have an errata document,
but I can't find a link to it anywhere on their site to include here.

Some of the S29GL064N chips report 64 sectors when they should report 128,
and some of S29GL032N chips report 127 sectors when they should report 63.

Note that when the chip dies are fixed by Spansion, they will still have
the same id.  The fix is done in such a way that it won't affect corrected
chips.

The fixups use the extended id made available by a previous patch.  Without
that, virtually all newer AMD/Spansion chips will have the same ID (0x227e)
and it's not possible to apply the fixup to the correct chips.
