[flashrom] Gigabyte GA-M56S-S3 supported

[Estevo Paz Freire]

Hi,

First at all, thanks for your program.

I updated successfully the mainboard GA-M56S-S3,
this is a dual bios mainboard so --chip option is needed.

$ flashrom --programmer internal -w /home/estevo/Downloads/M56SS3.F6h -c SST25VF040B

Best, estevo.
