grunt: Adjust serial config
Adjust the coreboot serial config so that grunt works correctly. Since
grunt is the only board supporting U-Boot we can do this globally for now.
BUG=chromium:837018
BRANCH=grunt
TEST=FW_NAME=grunt USE="altfw u-boot tianocore -cb_legacy_tianocore em100-mode" \
emerge-grunt --nodeps -q u-boot depthcharge chromeos-bootimage
See that we can boot into U-Boot from the menu and the display and UART
work.
