mb/google/guybrush: Enable PSP port 80s
Let's re-enable PSP post codes when running PSP verstage. The original
reason we disabled POST codes was that it was causing problems during
eSPI init in bootblock. Since we now init eSPI in PSP verstage, it's
safe to re-enable them. We can now see post codes during S0i3 enter and
exit. This will help when debugging resume or suspend hangs.
Port 80 writes on suspend:

Port 80 writes on resume:
