The M29W800DT parts also report their geometry with the sector layout
reversed. So add that ID to the flash_fixup_stm function.
Otherwise, we get:
bfin> flinfo
Bank # 1: CFI conformant FLASH (16 x 16) Size: 1 MB in 19 Sectors
AMD Standard command set, Manufacturer ID: 0x20, Device ID: 0x22D7
Erase timeout: 8192 ms, write timeout: 1 ms
Sector Start Addresses:
20000000 20004000 20006000 20008000 20010000
20020000 20030000 20040000 20050000 20060000
20070000 20080000 20090000 200A0000 200B0000
200C0000 200D0000 200E0000 200F0000
