[flashrom] Flashrom experimental chip support report

[Sadoon Albader]

Hi, I just flashed a firmware image to a "XM25QH64C" which is labeled 
experimental, the flash was successful with default options on a ch341a_spi 
clone, here is the log. Sorry I couldn't get the debug output. Reading and 
writing worked just fine. Thanks a lot for maintaining this awesome software!

I used the git master branch version as of today.
