This CL adds CHIP_VARIANT_NPCX7M6G to support another npcx7 ec SKU. Please note that the default setting in npcx7_evb is npcx7m6f. For the EVB using the 128-pins EC package, please change CHIP_VARIANT from npcx7m6f to npcx7m6g in build.mk. BRANCH=none BUG=none TEST=No build errors for make buildall; Set CHIP_VARIANT=npcx7m6g in board/npcx7_evb/build.mk; Build the image and test on EVB.
