[flashrom] Chip size

[EvilGremlin]

Hello!

Can you change chip size verification? At least for SPI EEPROMs, that i 
flash almost every day, chip size doesn't really matter. I find it 
really annoying, that i cannot flash 32Mb image to 64Mb chip and there 
is no option to force it. So i have to boot Windows or edit image just 
for that. Almost any other software can do that just fine.

So, can you add force key or warning message with (yes/no) option. 
Default "yes", of course.
