cfi_flash: Support buffered writes on non-standard Spansion NOR flash
Some NOR flash chip from Spansion, for example, the s29ws-n MirrorBit series require different addresses for buffered write commands. Define a configuration option to support buffered writes on those chips. A more elegant solution would be to automatically detect those chips by parsing their CFI records, but that would require introduction of a fixup table into the cfi_flash driver.
