[flashrom] [PATCH] Add support for GD25VQ21B, GD25VQ40C, GD25VQ80C and GD25VQ16C

Hello,

Whitespace and other issues have been fixed. Sadly, test status still remains untested due to delay in shipment of some components :( Shipment delivey has become unreliable so I will not be giving an estimate for that, but once it arrives, I will test and send patches the same day.

Stefan, this patch does not include some other changes you had introduced because I thought those changes were not related to the above commit message ;)

Thanks :)
