flash_ec: stm32/npcx_uut: Set ec_boot_mode to off on exitstabilize-nocturne.10736.Bstabilize-atlas.10736.B
The ec_boot_mode is used for flashing EC on STM32 and NPCX chips.
The ec_boot_mode pin is an open-drain GPIO. Doing save/restore is
destructive. For example, if DUT is unpowered (ec_boot_mode is "on"),
doing save/restore will force it outputting to "on". We should not
put it to the save/restore list. Instead, set it back to "off" on
exit.
BRANCH=none
BUG=b:80305869
TEST=Ran flash_ec when DUT is unpowered -> failed as expected.
Reran again when powered. Checked EC UART showed-up afterward.
