Use a distinct return code for SPI commands with unsupported/invalid length
Some drivers support only a few combinations of read/write length and return error otherwise. Having a distinct return code for this error means we can handle it in upper layers. Corresponding to flashrom svn r653. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Stefan Reinauer <stepan@coresystems.de>
