servo_micro: add programmable serial number
This change provides a console command for setting,
and loading a usb serial number from flash. This
feature adds CONFIG_USB_SERIALNO, and currently only
has a useful implementation when PSTATE is present.
BUG=chromium:571477
TEST=serialno set abcdef; serialno load; reboot
BRANCH=none
