futility: updater: Add '--servo_port' to select from multiple servods
When multiple servo boards are connected to the host, we usually want to
select the right servo by specifying its port, get the servo serial
number, and pass that to flashrom programmer.
The new --servo_port (or environment variable SERVOD_PORT) now allows
developers to flash firmware via specific servod using futility updater
easily:
futility update --servo_port 9998 -i PATH_TO/image.bin
BRANCH=None
BUG=None
TEST=make runtest; sudo futility update --servo_port 9998 -i image.bin
