mb/google/dedede/var/bugzzy: Initialize display signals on user mode
Bugzzy uses panel-built-in touch screen, it needs to set panel power
and reset signal to high for touch screen to work.
On user mode, coreboot doesn't initialize graphics since there is no
screen display before OS. So we would add a WA to initialize required
signals on user mode. It takes under 30 ms delay on booting time.
BUG=b:205496327
BRANCH=dedede
TEST=Verified touch screen worked with test coreboot
and test touch screen 028D firmware
