Hello Laurentiu,

Thanks for your work.

This flag was added as I could not find the register in the MAX96724 
datasheet I had access to at the time. As you now prove the register 
exists in the user's guide and that it works I think a better solution 
is to remove the 'have_debug_extra' flag all together then set it for 
both supported devices.
