[flashrom] Programatically check/reduce the programming voltage

[Miklos Marton]

Hello all,

I have successfully managed to fry one W25Q64FW (1.8V only) SPI flash by 
using the default 3.3V programing voltage.

The flash chip had been detected successfully from the 3.3V supply 
voltage, but I needed to run several failed programming attempts before 
I have started to look into the datasheet.
To prevent such an accidents I would like to implement a check after the 
device detection to automatically reduce the programming voltage if 
needed. I know that only one programmer (dediprog) uses this at the 
moment, but I have been working for a while on adding support for an 
another one which would support this.

If you have any objections/recommendations please let me know!
