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.
