flashchips.c: Put SFDP-capable chip back into position

Put entry for Unknown SFDP-capable chip back into place at end of file.

Change 1f9cc7d89992114c70f7a0545ad9f98701bebe56 "flashchips.c: Sort file
by vendor and model" reordered many entries in flashchips.c, including
this one. However, the entry for Unknown, SFDP-capable chip should not
have been moved before any specific chip entries.

As reported by Angel Pons <th3fanbus@gmail.com> at
https://review.coreboot.org/c/flashrom/+/33931:

"""
Oops, this introduced a bug: the SFDP entry is no longer at the end of
flashchips.c, so probing on a SFDP-capable Winbond chip results in added
noise (flashrom says things about an unknown chip, and then has two
definitions for the same chip).
