Todd Broch abc11d883c stm32: Force disconnect of UART prior to writing firmware.

For chromeos devices with the stm32 EC we write the firmware via
uart.  Often developers are connected to this UART for console I/O
which causes flash_ec to fail.

This change looks for any pids currently attached to the UART and
forcibly kills them prior to attempting to write the firmware.

BRANCH=spring
BUG=none
TEST=manual,

./util/flash_ec --board spring ...

Forcibly grabs UART from both:
  cu -l /dev/pts/<num>
  minicom -p /dev/pts/<num>
