Add support for S25FL128P, S25FL129P and refine it for S25FL128S chips

Additionally to the existing S25FL128S......0 definition this patch
adds S25FL128P......0, S25FL128P......1 and S25FL128S......1, as well as
S25FL129P......0 and S25FL129P......1 definitions.
S25FL12xP seem to be the predecessor families of S25FL128S. All
associated chips can not be distinguished with RDID alone.

Besides the new chips, this patch also fixes the name of the  previously
supported S25FL128S model with uniform 256 kB sectors
(S25FL128P......1 not 0) and adds the hybrid sector version (0) as well.

Due to the shared IDs the user has to select the right chip manually
with the -c parameter. To make this even possible, this patch enlarges
the respective array for results to 6.

Tested-by: Antonio Ospite <ao2@ao2.it>
with a S25FL129P......0.

Corresponding to flashrom svn r1838.
