flash_ec: On C2D2 disable EC flashing mode when finished
The mux switching C2D2 between I2C and EC console remains in the EC
programming mode, resulting in cutting access to EC and GSC consoles
after ITE EC programming is finished.
Disabling the programming mode after programming is completed restores
access to the consoles.
BRANCH=none
BUG=b:243076325
TEST=successfully programmed EC on Nereid and Nivviks devices over
C2D2, EC console remained available after programming was
completed.
