futility: update: Add --programmer to override flashrom programmer for servo
Many developers need to reflash or update firmware using servo, and the
firmware logic has been complicated enough that simply calling
'flashrom -w image.bin -p $SERVO' will usually destroy many important
settings, for example HWID, VPD, and other data provisioned in factory.
It should be more convenient if we can use 'futility update' against
servo. The '--programmer' provides first step - to override the flashrom
programmer so we can read and write via special programmer (like servo).
With this change, developers can reflash using:
futility -p $SERVO -i $IMAGE --force --wp 0
