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
Erase timeout: 8192 ms, write timeout: 1 ms
