cfi_flash: reverse geometry for M29W800DT parts

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
