mb/google/brya/var/bb/brask: enable HDMI gpios early
Add some HDMI-related gpios that are needed for early sign-of-life
to the early_graphics_gpio_table array so that SOL will show up on
HDMI ports.
BUG=b:277861633
BRANCH=firmware-brya-14505.B
TEST=`emerge-brya coreboot chromeos-bootimage` and verify it builds
without error.
