util: flash_ec: Add support to flash npcx7_evb with npcx7m7x chip

Browse Source 
This CL modified the flash_ec and openocd script to support flashing
npcx7m7x chip on npcx7_evb.

BRANCH=none
BUG=none
TEST=Change CHIP_VARIANT to npcx7m7w in board/npcx7_evb/build.mk;
"BOARD=npcx7_evb make"; Move npcx7_evb from array BOARDS_NPCX_7M6X_JTAG
to BOARDS_NPCX_7M7X_JTAG in util/flash_ec; Connect servo JTAG to npcx7
EVB; "./util/flash_ec --board=npcx7_evb"; Make sure the programing
succeed and EVB bootup.
