flash_ec: For npcx_uut, use servo to boot EC into the flashing mode
Use servo to boot EC into the flashing mode. Use the unified control
ec_boot_mode to do so.
CQ-DEPEND=CL:1018206
BRANCH=none
BUG=b:68707064
TEST=Ran the flash_ec script on Cheza using servo-micro
TEST=Ran the flash_ec script on Meowth using CCD, with some servo
overlays to drive the ccd_ec_boot_mode control
