stm32mon: add back flashing progression

Browse Source 
As we no longer have the low-tech dots to show the progression of the
on-going flashing, display a completion percentage to give the user a
hint of the ETA.

Signed-off-by: Vincent Palatin <vpalatin@chromium.org>

BRANCH=none
BUG=none
TEST=./util/flash_ec --board=spring
and see accurate progression percentage reported.
