[flashrom] Supporting GD25LB64CVIG

[Renato Kristić]

Hello,

I'd like to flash  *GD25LB64CVIG*  but I cannot see that it is shown in the
list of supported chips.
Would it be possible to add support for this chip?

If not, is there any guide that can help me to manually add support for
this chip.

Best Regards,
